Solve $( y - 5 ) ^ { 2 } = 144$ by the Square Root Property, if possible.
A) $y = 12 , y = - 12$
B) $y = 17 , y = - 7$
C) y=139
D) $y = - 17 , y = - 7$
E)no solutions

Quizplus · Accepted Answer

Taking the square root of both sides of the equation, we get $y - 5 = \pm 12$. Solving for $y$, we get $y = 17$ and $y = -7$. Hence, the answer is $\boxed{	extbf{(B)}\ y = 17 , y = - 7}$.

Solve (y−5)2=144( y - 5 ) ^ { 2 } = 144(y−5)2=144

Solve $( y - 5 ) ^ { 2 } = 144$
