Solving a quadratic by factoring | Quadratic equations | Algebra I | Khan Academy. Watch later. Every quadratic equation has two values of the unknown variable, usually known as the roots of the equation (α, β). We can obtain the roots of a quadratic equation by factoring the equation. For this reason, factorization is a fundamental step towards solving any equation in mathematics.
STEP 1: Perform the FOIL Mehtod. Perform the FOIL method on the left-hand side of the equation.
