Quizplus · Accepted Answer

Taking the square root of both sides of the equation $(4x+4)^2 = 64$ gives $4x + 4 = \pm 8$. Solving for $x$ when $4x + 4 = 8$ gives $x = 1$, and solving for $x$ when $4x + 4 = -8$ gives $x = -3$.

Solve the Equation (4x+4)2=64(4 \mathrm{x}+4)^{2}=64(4x+4)2=64 A) 1,−31,-31,−3 B) 1,3 C) 0,1 D) 17,−1717,-1717,−17
