How to solve a quadratic equation

Learn how to solve a quadratic equation by factoring when a is not 1. To factor an algebraic expression means to break it up into factors (expressions that can be multiplied together to get the original expression). To factor a quadratic trinomial where the coefficient of the squared variable is not 1, we find two factors of the product of the constant term (the term with no variable) and the coefficient of the squared variable whose sum gives the linear term. These factors are now placed in separate brackets with x to form the factors of the quadratic equation.

There are other methods that can be used to achive this including the AC, Berry, Box, Grouping, diamond and mental technique. Once we have factored the quadratic equation, we then apply the product property to solve our equation. When solving a quadratic equation we call our solutions the zeros, x-intercept, and roots.
