Question 292

Multiple Choice

Solve the equation by extracting the square roots.
- $( 2 x + 4 ) ^ { 2 } = 121$

A) $x = - \frac { 15 } { 2 }$ or $x = \frac { 13 } { 2 }$
B) $x = - 15$ or $x = 7$
C) $x = - \frac { 15 } { 2 }$ or $x = \frac { 7 } { 2 }$
D) $x = \frac { 7 } { 2 }$ or $x = \frac { 13 } { 2 }$

Solve the Equation by Extracting the Square Roots (2x+4)2=121( 2 x + 4 ) ^ { 2 } = 121(2x+4)2=121
