Table of Contents Quadratic Equation: Solving Using the Quadratic Formula Example: Solve 2x 2 + 4x = 1. The quadratic formula is Here, a, b, and c refer to the numbers when the quadratic is in standard form, ax 2 + bx + c = 0. First, put the equation in standard form. 2x 2 + 4x – 1 = 0 Next, substitute the values a = 2, b = 4, and c = -1 into the formula.
