Question: how to solve quadratic equation for x?
Answer: Quadratic Equation in Standard Form: ax2 + bx + c = 0. Quadratic Equations can be factored. Quadratic Formula: x = −b ± √(b2 − 4ac) 2a. When the Discriminant (b2−4ac) is: positive, there are 2 real solutions. zero, there is one real solution. negative, there are 2 complex solutions.
