Question

Determine which equation has the same solutions as the given equation. x2 − 10x − 11 = 0 A. (x − 5)2 = 36 B. (x − 10)2 = 21 C. (x − 10)2 = 36 D. (x − 5)2 = 21

Answer 1

A. (x - 5)² = 36

Explanation:

Step 1: Isolate x

x² - 10x = 11

Step 2: Complete the Square

x² - 10x + 25 = 11 + 25

(x - 5)² = 36

And we have our answer!
