Question

Can some one help? Please

Answer 1

hey so the answer for that question is b

Answer 2

B

Explanation:

Given

x² + 2x + 1 = 17 ( subtract 1 from both sides )

x² + 2x = 16

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(1)x + 1 = 16 + 1

(x + 1)² = 17 ← take the square root of both sides

x + 1 = ±
`√(17)` ← subtract 1 from both sides

x = - 1 ±
`√(17)`
