- Write the equation in the form of: ax2 +bx +c = 0 a x 2 + b x + c = 0
- Factorize the quadratic and solve for the variable.
- Use quadratic formula if you couldn’t factorize the quadratic.
- Quadratic formula: x = −b± b2−4ac√ 2a x = − b ± b 2 − 4 a c 2 a

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.

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 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.
