Simplifying a complex rational
I am having a rather frustrating time simplifying this expression...
my first step as instructed by my pre-calculus textbook is to multiply [x^2(x+h)^2] to both the numerator and denominator as a result I see:
I think my treatment of fractions is the problem because my next action is to eliminate (x+h)^2 from the num. and denom. of the left expression and x ^2 from the num. and denom. of the right expression leaving me with:
this is my dead end and I know that the only reason I am here is because I cannot see past the error in my mind, please help me.
