I think your algebra could look more like:
( x + h ) 4 ( x + h ) 2 x 4 x 2 h ( x + h ) 4 ( x + h ) 2 + x 4 x 2 ( x + h ) 4 ( x + h ) 2 + x 4 x 2 = ( x + h ) 2 ( 4 ( x + h ) 2 ) x 2 ( 4 x 2 ) h ( ( x + h ) 4 ( x + h ) 2 + x 4 x 2 )
This leaves no radicals in the numerator.
In the numerator, once this is multiplied out, all h-free terms will have canceled out through adding terms to their negatives.
Then you can factor h from the top and cancel the h in the denominator. Then it will be OK to just let h 0

Calculate limit involving the antiderivative of a function
Let f : R R , f ( x ) = e x 2 . Now, consider F an antiderivative of f.
Calculate: lim x x F ( x ) f ( x ) .
I couldn't find the antiderivative of f, and besides finding F, I have no other ideas.

Most general antiderivative involving sec x
I'm stumped on how to get the most general antiderivative, F(x) , of f ( x ) = e x + 3 s e c x ( t a n x + s e c x ).
First, I split the equation on addition, since [ f ( x ) + g ( x ) ] d x = f ( x ) d x + g ( x ) d x
F ( x ) = e x d x + 3 s e c x ( t a n x + s e c x ) d x
Then I use the Substitution Rule. sec(x) seems like a good choice for u since it's the inner function of a composition and du will encompass the other x terms
u = s e c x d u = ( t a n x + s e c x ) d x
Then I have F ( x ) = e x + 3 ( u ) d u F ( x ) = e x + 3 u 2 2 + C F ( x ) = e x + 3 s e c 2 x 2 + C
However, the answer key says the correct answer is F ( x ) = e x + 3 s e c x + 3 t a n x + C.
Can someone please point out where I've gone wrong here?
