What values of x make the equation x^2 + 9x – 22 = 0 true? check all that apply.

–11

–2

0

2

11

x = 2 , - 11.

Step-by-step explanation:

Given  : x² + 9x – 22 = 0

To find : What values of x make the equation.

Solution : we have given  x² + 9x – 22 = 0

On factoring

x² + 11x - 2x – 22 = 0 .

Taking common x from first two term and -2 from last two terms.

x ( x +11) - 2 (x +11) = 0.

On grouping

(x -2) (x +11) = 0

For

x - 2  =0

x = 2 .

For

x + 11 = 0

x = -11.

Therefore, x = 2 , - 11.
