Question

Find the value of this expression if x = -9.

Answer 1

-15

Explanation:

Note that it says x = -9. Plug in -9 for all x inside the expression and solve.

(x² + 9)/(x + 3) = (-9² + 9)/(-9 + 3)

Solve. First, solve the parenthesis, then divide:

(-9² + 9) = (81 + 9) = 90

(-9 + 3) = (3 - 9) = -6

Divide:

(90)/(-6) = -15

-15 is your answer.
