For what values of x does (x + 9)^2 - 36 = 0 A. {3, 15} B. {-3, -15} C. {-2/3, -4/5} D. {-45}

For what values of x does (x + 9)^2 - 36 = 0
A. {3, 15}
B. {-3, -15}
C. {-2/3, -4/5}
D. {-45}

Answer

To solve the equation (x + 9)^2 - 36 = 0, we first set it equal to zero:

(x + 9)^2 = 36

Taking the square root of both sides gives:

x + 9 = ±6

Solving for x, we get:

  1. x + 9 = 6 → x = 6 - 9 = -3
  2. x + 9 = -6 → x = -6 - 9 = -15

Therefore, the values of x are {-3, -15}, which corresponds to option B.
