1 3.2 Chapter 3 Quadratic Equations

2 To solve quadratic equations by factoring, apply the which states that, if the product of two real numbers is zero, then one or both of the numbers must be zero. Thus, if, then x x + 16 = 0. Solve the following: x 2 + 8x = 0. Solving Quadratic Equations 3x x - 14 = 0

3 Solve the following by factoring: a) 3x x = 81b)3x = x(x + 13)
