1 Explain in complete sentences. in why the equation has two solutions. Then solve the equation to find the solutions. ( + 3) ^2 + 8 = 72

2 This is Mrs. Galicia’s solution for the equation ^2 − 8 − 9 = 0:
^2 − 8 − 9 = 0
^2 − 8 = 9
^2 − 8 + 16 = 9 + 16
( − 4)^2 = 25
− 4 = 25 = 29
− 4 = −25
= −21
Is Mrs. Galicia’s solution correct? Explain in complete sentences.
