Answer:
c = -9 ±√8
Step-by-step explanation:
You can solve for (c+9)²=64 by using inverse operations. Since the expression (c + 9) is under the operation of squaring, use a square root on both sides to undo it. Then continue using inverse operations to solve for C.
(c+9)²=64
√(c+9)² = √8
(c + 9) = ±√8
c = -9 ±√8
