Question

What values of x make the equation x2 + 9x – 22 = 0 true? Check all that apply.

Answer 1

-11 and 2.

Explanation:

I am assuming that this question is
`x^(2)`+9x-22 = 0

A few ways to answer:

You can graph and look at the x intercepts. They are at (-11,0) and (2,0).

You can also rewrite the equation like this:

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

So that means that for this equation to equal zero, either:

X+11 = 0

OR

x-2 = 0

Again, the same answers as graphing: x is -11 or x is 2.

Answer 2

`x^(2) +9x-22=0\\(x-2)(x+11)=0\\x-2=0 ; x+11=0\\x=2, x=-11`

All possible values for x is 2 or -11.
