Answer:
y = 0 or y = -4
Step-by-step explanation:
Solve for y over the real numbers:
(4 y + 8)^2 = 64
Take the square root of both sides:
4 y + 8 = 8 or 4 y + 8 = -8
Subtract 8 from both sides:
4 y = 0 or 4 y + 8 = -8
Divide both sides by 4:
y = 0 or 4 y + 8 = -8
Subtract 8 from both sides:
y = 0 or 4 y = -16
Divide both sides by 4:
Answer: y = 0 or y = -4
