• Factorize the quadratic and solve for the variable.
• Quadratic formula: x = −b± b2−4ac√ 2a x = − b ± b 2 − 4 a c 2 a

### Which are the solutions of the quadratic formula?

The solutions to the quadratic equation are the values of the unknown variable x , which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

### What is the correct quadratic formula?

The quadratic formula is a technique that can be used to solve quadratics, but in order to solve a quadratic using the quadratic formula the problem must be in the correct form. To solve a quadratic using the quadratic formula the quadratic must be in the form ax2 + bx + c = 0.

### How do you simplify the quadratic formula?

How To Simplify a quadratic formula result. The first thing you have to do when given the quadratic equation is bring all the terms to one side so that you have a zero on the other side of the equals to sign. Now the formula to calculate the roots of the quadratic equation ax*x + bx + c = 0 is x = (-b + root of (b*b - 4*a*c) ) / 2 * a.
