hint: 

Difference of squares
a^2 - b^2 = (a-b)(a+b)

alexandervonhumboldt2 · Answer

so you have as @iambatman   and @jim_thompson5910   said 
you have to simplify this thing: (x+2)/((x+2)*(x-2))  let us know what you get

jim_thompson5910 · Answer

iambatman, you have g and f mixed up

Oops!

anonymous · Answer

$$\frac{ g(x) }{ f(x) }=\frac{ (x^2-4) }{ (x+2) }$$ nice catch jim!

How do i know that excluded value? I got the answer x-2 for the problem. Im just missing the excluded value..Help Pleasee

anonymous · Answer

I actually just figured out the excluded value is -2(: Thanks guys!

jim_thompson5910 · Answer

you cannot divide by zero

so if the denominator is zero, then x+2 = 0 leads to x = -2 like you got
