A.8A-7B Solving Quadratics

• There are two zeros, -242 and 242, which can be found when 0 = (x + 242)(x - 242).

• There are two zeros, -22 and 22, which can be found when 0 = (x + 22)(x - 22).

• There are two zeros, -162 and 162, which can be found when 0 = (x + 162)(x - 162).

• There are two zeros, -18 and 18, which can be found when 0 = (x + 18)(x - 18).
