Answer:

x + 9/ x + 4

Explanation:

x^2+5-36/X^2-16

Factor x^2+5x−36x^2+5x-36 using the AC method.

Write the factored form using these integers.
(x−4)(x+9)/x^2−16

Simplify the denominator.

(x−4)(x+9)/x^2−42

Since both terms are perfect squares, factor using the difference of squares formula

(x−4)(x+9)/(x+4)(x−4)

Cancel the common factor of x−4.

Rewrite the expression.
(x+9)/(x+4)

And your answer turns out to be (x+9)/(x+4)


I hope it helps!
