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!
