Quadratic Equation x = (-b ± √b^2 - 4ac) / 2a Where a = Numerical Coefficient of First Term b = Numerical Coefficient of Middle Term c = Numerical Coefficient of Last Term For Example: x^2 + 2x + 1 a=1 b=2 c=1
x = (-b ± √b^2 - 4ac) / 2a x = (-2 ± √4-4) / 2 x = (-2 ± 0) / 2 x sub 1 = (-2 + 0) / 2 x sub 2 = (-2 - 0) / 2 x sub 1 = -2 / 2 x sub 2 = -2 / 2 x sub 1 = -1 x sub 2 = -1 So, x = 1
