Homework Help: Calculus

Posted by -Untamed- on Friday, December 23, 2011 at 5:52pm.

Simplify. State the nonpermissible values.

4a^2-1/4a^2-16*2-a/2a-1

This is what I did to try and solve it out:

(2a+1)(2a-1)/(2a+4)(2a-4)*2-a/(2a-1)

I cancelled out the (2a-1)'s and don't get how to solve.

I'm supposed to get the answer :

-2a-1/4(a+2)

But I don't get how to get that^.
