Question

Which of the following is a solution of x^2 − 10x = −36?

A. -5 - i srt.10

B. 5 + i sqt.61

C. -5-i srt. 11

D. 5+i srt. 11

Answer 1

x² - 10x = -36

x² - 10x + 36 = 0

x² - 2(5x) + 25 + 11 = 0

(x-5)² + 11 = 0


(x-5)² = -11

(x-5) = √(-11)

x = 5 + i√11

I believe the answer to your question is going to be

D)5+i srt.11

HOPE THIS HELPS!!

Answer 2

I think it’s D I’m not 100 percent sure
