The expression x^2-9/x^2+6x+8 is equal to zero when x =

x=-3  and x=+3

Step-by-step explanation:

x^2-9/x^2+6x+8 is equal to zero

We need to solve for x

Multiply the denominator on both sides

x^2 - 9 =0

add 9 on both sides

x^2 = 9

Take square root on both sides

x = +- 3

So , x=-3  and x=+3

answer: the answer is one
