For a quadratic equation in the form: ax² + bx + c = 0
The quadratic formula comes from completing the square of the quadratic equation that gives you a result of x=-b±√b²-4ac divided by 2a.
Using a simple quadratic equation like x² + 2x + 1 = 0
a=1; b=2; c=1
x=-2±√2²-4(1)(1) divided by 2a
x=-2±√4-4 divided by 2a (4 - 4 = 0 and the square root of 0 is 0)
Therefore, x=-2
