Quadratic Equation Solver

Quadratic equations have the form ax2 + bx + c = 0. Images

They will generally have two solutions; that is, two different
values of x that make the equation true.It can happen that
both solutions are the same number, and it is possible that
the solutions will be complex or imaginary numbers.

Type in values for a, b, and c in the boxes below, and press
the Solve button. You may enter positive, negative, or zero
values, but the value of a cannot be zero. A blank or non-numeric character is
treated as a zero.

The Plot button will open a new window that will allow you to plot quadratic
functions.

Input:
