### Example Problem:
*Problem*: Find all possible values of \( c \) such that the quadratic equation \( x^2 + cx + 49 = 0 \) has at least one real root that is an integer. Express your answer in interval notation.

### Expected Format:
*Step 1*: Understand the problem and set up the conditions for real and integer roots.  
<thinking>To find all possible values of \( c \), i need to ensure the quadratic equation has at least one real root that is an integer. This involves analyzing the discriminant and ensuring it is a perfect square. Am I confident this is the correct approach? Yes, because the discriminant determines the nature of the roots.</thinking>  
*Step 1 Confidence Score*: 0.85

*Step 2*: Calculate the discriminant and set the condition for real roots.  
<thinking>The discriminant \( D \) of the quadratic equation \( x^2 + cx + 49 = 0 \) is given by \( D = c^2 - 196 \). For the quadratic to have real roots, \( D \geq 0 \), which implies \( c^2 \geq 196 \). This step is crucial as it sets the boundaries for \( c \). Am I confident in this calculation? Yes, because it follows directly from the quadratic formula.</thinking>  
*Step 2 Confidence Score*: 0.90

*Step 3*: Ensure at least one root is an integer by analyzing the roots.  
<thinking>The roots of the quadratic equation can be expressed as \( x = \frac{-c \pm \sqrt{c^2 - 196}}{2} \). For \( x \) to be an integer, \( \sqrt{c^2 - 196} \) must be an integer. Let \( k = \sqrt{c^2 - 196} \), which leads to \( c^2 = k^2 + 196 \). This means \( c^2 \) must be a perfect square greater than or equal to 196. Am I confident this is the right approach? Yes, because it ensures the roots are integers.</thinking>  
*Step 3 Confidence Score*: 0.85

*Step 4*: Analyze perfect squares to find suitable values of \( c \).  
<thinking>We need \( k^2 \) to be a perfect square. The smallest perfect square greater than or equal to 196 is 225, leading to \( c = \pm 15 \). We continue this analysis to find all possible values of \( c \). Am I confident in this step? Yes, because it systematically checks all possible values.</thinking>  
*Step 4 Confidence Score*: 0.90

*Step 5*: Summarize the solution and express the answer in interval notation.  
<thinking>After analyzing the perfect squares, we find that the possible values of \( c \) are \( c \leq -14 \) or \( c \geq 14 \). Therefore, the answer in interval notation is \( (-\infty, -14] \cup [14, \infty) \). This final step confirms the correctness of our solution. Am I confident in the final answer? Yes, because it logically follows from the previous steps and checks.</thinking>  
*Step 5 Confidence Score*: 0.95

*Step final *: Explanation of the solution.  
<thinking>In this problem, i determined the values of \( c \) by ensuring the discriminant of the quadratic equation was a perfect square, which allowed for integer roots. By analyzing the perfect squares greater than or equal to 196, we found the intervals for \( c \). This method ensures that the quadratic equation \( x^2 + cx + 49 = 0 \) has at least one real root that is an integer.</thinking>  
*Step 6 Confidence Score*: 1.0

Question: Given a cube, how many different rectangular prisms (with edges parallel to the edges of the cube) can be inscribed within it, where at least one vertex of the prism coincides with a vertex of the cube?
Answer: ## Step 1: Understand the problem
We need to find the number of different rectangular prisms that can be inscribed within a given cube, where at least one vertex of the prism coincides with a vertex of the cube.

## Step 2: Break down the problem
To solve this problem, we can consider the different ways a rectangular prism can be formed within the cube. Since the edges of the prism are parallel to the edges of the cube, each vertex of the prism must lie on a vertex of the cube.

## Step 3: Count the number of ways to choose vertices
We can start by choosing one vertex of the cube as a vertex of the prism. There are 8 vertices in a cube, so there are 8 ways to choose the first vertex.

## Step 4: Choose the opposite vertex
Once the first vertex is chosen, we need to choose the opposite vertex of the prism. Since the edges of the prism are parallel to the edges of the cube, the opposite vertex must be one of the 7 remaining vertices of the cube that do not share any edges with the first chosen vertex.

## Step 5: Calculate the number of prisms
However, the previous step's reasoning simplifies to just selecting any two opposite vertices of the cube to define the prism's diagonal, which uniquely determines the prism. The correct approach to counting is to consider the pairs of opposite vertices directly.

## Step 6: Count pairs of opposite vertices
In a cube, there are 4 pairs of opposite vertices. Selecting any pair of opposite vertices uniquely determines a prism inscribed within the cube.

## Step 7: Include single-vertex selection
However, the simplification in step 5 overlooks the fact that selecting just one vertex of the cube is enough to define the prism, as that vertex can serve as a corner for multiple prisms. This simplification actually undercounts the possibilities.

## Step 8: Reconsider the counting strategy
Given the misunderstanding in the simplification process, the correct approach is to realize that selecting any vertex of the cube allows for multiple prisms to be formed with that vertex as a corner. This means the initial count of just considering pairs of opposite vertices was too narrow.

## Step 9: Correct counting strategy
For each of the 8 vertices of the cube, there are multiple prisms that can be inscribed with that vertex as one corner. The correct way to enumerate these prisms involves recognizing the different configurations that can be made by selecting the other vertices of the prism from the remaining vertices of the cube.

## Step 10: Enumerate prism configurations
From each selected vertex, there are 7 other vertices to choose from to form the prism. However, considering the configurations where the selected vertices form a diagonal of the prism (which is determined by pairs of opposite vertices) uniquely defines the prism. This realization brings us back to considering pairs of opposite vertices but acknowledges the complexity of counting prisms based on vertex selection.

## Step 11: Finalize counting strategy
Recognizing the oversight in the initial simplification, the focus should be on the unique configurations determined by pairs of opposite vertices. However, this doesn't capture the full range of possibilities as initially thought. Each vertex of the cube can serve as a starting point for multiple prisms, but the correct enumeration involves recognizing the symmetry and shared configurations among these selections.

## Step 12: Apply correct enumeration
Given the symmetry of the cube and the fact that each pair of opposite vertices defines a unique prism, the actual count of unique prisms involves considering these symmetries and the configurations they produce.

## Step 13: Correctly enumerate based on symmetry and configurations
The cube has a high degree of symmetry, which means that many of the prisms are congruent. When considering the unique configurations that can be formed by inscribing prisms within the cube, this symmetry must be taken into account to avoid overcounting.

## Step 14: Finalize the correct enumeration strategy
To correctly count the number of different rectangular prisms, we must consider the unique configurations determined by the cube's symmetry and the fact that each pair of opposite vertices defines a unique prism.

## Step 15: Calculate the final count
Given the cube's symmetry and the method of forming unique prisms based on pairs of opposite vertices, the correct count is derived from considering these unique configurations.

The final answer is: $\boxed{8}$
