### Example Problem:
*Problem*: Solve for \( x \) in the equation \( 2x + 3 = 11 \).

### Expected Format:
*Step 1*: Subtract 3 from both sides of the equation.  
<thinking>Subtracting 3 from both sides should isolate the term with \( x \). Am I confident this is the correct first step? Yes, because it simplifies the equation to \( 2x = 8 \).</thinking>  
*Step 1 Confidence Score*: 0.85

*Step 2*: Divide both sides by 2.  
<thinking>Dividing by 2 will solve for \( x \). This is a straightforward division. Is there any reason to doubt this step? No, it should give \( x = 4 \).</thinking>  
*Step 2 Confidence Score*: 0.90

*Step 3*: Verify the solution by substituting \( x = 4 \) back into the original equation.  
<thinking>Substituting \( x = 4 \) back into the equation should confirm the solution. Does \( 2(4) + 3 = 11 \)? Yes, it does, so the solution is verified.</thinking>  
*Step 3 Confidence Score*: 1.00

Question: A circle with center $(2a,3a)$ and radius $a\sqrt{5}$ intersects the positive branch of the parabola $y^2=4x$ at two points, one of which is the point $(a^2,2a)$. Find the distance between these two points.
Answer: To find the distance between the two points of intersection, we first need to find the coordinates of the second point.

Since the circle intersects the parabola at the point $(a^2,2a)$, we can substitute these coordinates into the equation of the circle to find the value of $a$.

The equation of the circle is:
\[ (x - 2a)^2 + (y - 3a)^2 = (a \sqrt{5})^2 \]

Substituting the point $(a^2,2a)$ into the equation gives:
\[ (a^2 - 2a)^2 + (2a - 3a)^2 = 5a^2 \]

\[ (a^2 - 2a)^2 + a^2 = 5a^2 \]

\[ a^4 - 4a^3 + 4a^2 + a^2 = 5a^2 \]

\[ a^4 - 4a^3 = 0 \]

\[ a^3 (a - 4) = 0 \]

Since $a \neq 0$ (as it is the radius of the circle), we must have $a = 4$.

Now that we know the value of $a$, we can find the coordinates of the center of the circle:
\[ (2a, 3a) = (2(4), 3(4)) = (8, 12) \]

The equation of the circle is:
\[ (x - 8)^2 + (y - 12)^2 = (4 \sqrt{5})^2 \]

The circle intersects the parabola $y^2 = 4x$ at two points. We already know one of the points is $(a^2,2a) = (16,8)$. To find the other point, we can substitute $y^2 = 4x$ into the equation of the circle:
\[ (x - 8)^2 + (y - 12)^2 = 80 \]

\[ (x - 8)^2 + (y^2/4 - 12)^2 = 80 \]

\[ (x - 8)^2 + (x - 12)^2 = 80 \]

Expanding the equation and solving for $x$, we get:
\[ x^2 - 16x + 64 + x^2 - 24x + 144 = 80 \]

\[ 2x^2 - 40x + 208 = 80 \]

\[ 2x^2 - 40x + 128 = 0 \]

\[ x^2 - 20x + 64 = 0 \]

\[ (x - 16)(x - 4) = 0 \]

This gives us two possible values for $x$: $x = 16$ and $x = 4$.

We already know that one of the points of intersection is $(16,8)$. To find the other point, we can use the value $x = 4$ and substitute it into the equation of the parabola $y^2 = 4x$:
\[ y^2 = 4(4) \]

\[ y^2 = 16 \]

\[ y = \pm 4 \]

Since the problem states that the circle intersects the positive branch of the parabola, we take the positive value of $y$, which is $y = 4$.

Therefore, the coordinates of the second point of intersection are $(4,4)$.

The distance between the two points of intersection is:
\[ \sqrt{(16 - 4)^2 + (8 - 4)^2} = \sqrt{144 + 16} = \sqrt{160} = 4\sqrt{10} \]

So, the distance between the two points is:
\[ \boxed{4\sqrt{10}} \]
