# Solve Quadratic Equations - Calculator and Solver

An easy to use online calculator and solver for quadratic equations of the form

^{2}+ b x + c = 0

_{ 1}= [- b + √D ] / 2a and x

_{ 2}= [- b - √D ] / 2a

to calculate the solutions of the quadratic equation. The discriminant D given by

^{ 2}- 4ac

The solutions given by this calculator may be real or complex numbers. In the case of real numbers, the imaginary part is equal to zero.
