Hello all, I have been having some trouble grasping the quotient rule. Here's a sample problem, and I'll point out where I get tripped up.
1) all over (I couldn't find the right LaTeX command to divide the entire function by )
2) all over
3) I divided from in the numerator, and then combined like terms.
----I think I see where I went wrong. When I divide in the denominator, I need to also do it to ?; the book's answer is .
I guess what I'm asking is if my answer in part 3 is correct assuming the book's is just another way to simplify the same problem?
