The numerator is a difference of two squares: .
The problem is:
(sqrt(x-5)-sqrt(5))/(x-10)x(sqrt(x-5)+sqrt5)/(sqrt(x-5)+sqrt5)
This link shows exactly what the equation looks like
(sqrt(x-5)-sqrt(5))/(x-10) (sqrt(x-5)+sqrt5)/(sqrt(x-5)+sqrt5 - Wolfram|Alpha)
The complete steps for FOIL on the numerator is what i'm stuck on. I know the numerator will be (x-5)-5 after the numerator is solved and thereon i know what to do.
thanks
