Answer 1

B

Explanation:

x² + 9x - 22

consider the product of the factors of the constant term (- 22) which sum to give the coefficient of the x- term (+ 9)

the factors are + 11 and - 2 , since

11 × - 2 = - 22 and 11 - 2 = + 9 , then

x² + 9x - 22 = (x + 11)(x - 2)

Answer 2

`{x}^(2) + 9x - 22 \\ = (x + 11)(x - 2)`

OPTION B MATCHES AS THE SOLUTION.
