This lesson teaches how to solve quadratic equations in standard form using the quadratic formula and factoring. The first step is to simplify each side of the equation so that it can be put in standard form. Next, the quadratic formula is used to find the solutions. Alternatively, factoring can also be used to solve the equation. The lesson walks through step-by-step how to use both methods, and emphasizes the importance of checking the solutions by plugging them back into the original equation.
