# 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.
