### May 7, 2019 #### A. Solving Quadratic Equations by Extracting Square Roots Here are the properties in how to solve: - If c = 0, then x2 = c has two real roots. - If c > 0, then x2 = c has one real root. - If c < 0, then x2 = c has no real roots. #### B. Solving Quadratic Equations by Factoring Steps in solving quadratic equations by factoring: 1. Transform the quadratic equation into standard form if necessary. 2. Factor the quadratic expression. 3. Apply the zero-product property by setting each factor equal to zero. 4. Solve each resulting equation. 5. Check the values obtained by substituting each in the original equation.
