Quadratic equation and solution

Quadratic equation and solution using the quadratic formula.

Given a, b, and c, this formula solves the equation ax^2 + bx + c, returning the value or values of x.
The formula used is the quadratic formula: x = ( -b ± sqrt( (b ^ 2) - 4ac) ) / (2a), where a ≠ 0.

a: b: c:    Resulting equation: 1 * (x ^ 2) + 0 * x + -1
Result:

discriminant = 4.00, x = 1.00 or -1.00
