Q:
# Use the square root property of equality to solve (x – 3)2 = –4. The solutions are a. -1 or 7 b. 1 or 5 c. 3+- 2i d. 3+-4i

Accepted Solution

A:

The answer is C. 3+-2i

(x-3)[tex] (x-3)^{2} = -4 \sqrt{(x-3)^2} = +- \sqrt{-4 x - 3 = i \sqrt{4} x - 3 = +-2i x = 3 +-2i[/tex]

(x-3)[tex] (x-3)^{2} = -4 \sqrt{(x-3)^2} = +- \sqrt{-4 x - 3 = i \sqrt{4} x - 3 = +-2i x = 3 +-2i[/tex]
