The quadratic equation:
x2 +x += 0
Discriminat: Δ  =
Quadratic formula: x1,2=
First root: x1   =
Second root: x2 =

In elementary algebra, a quadratic equation is any equation having the form: ax2 + bx + c = 0

In this equation the x is unknown, a, b, and c are constants number, they are non-zero number.

Quadratic Equation formula:

x =(- b ±√ b2 - 4 * a * c) / 2 * a
Discriminat = b2-4ac.

For example, when a = 2, b = 5, c = 9, Discriminat Δ = -47, x1,2 = (-5 ± √(-47))/(2×2), and the roots x1 = -1.25 + i1.7139136501, x2 = -1.25 - i1.7139136501.
