**Ax²+Bx+C=0**

X is a variable, and A, B, and C, constants, A needs to be different from zero for find a result in Quadratic Equation Calculator.

### Quadratic Equation Calculator – Quadratic formula

A quadratic equation with a complex /real/ coefficient has exactly two solutions, named roots. These solutions might be distinct, as well as they may not be real.

The two roots are given by the quadratic equation formula

The character “±” indicates that both (+ and -).

In a Quadratic Equation Calculator one root will use – and the another will use +.
