Math
In this problem: -2/a+2 + 3a/2a-1 First I made the denominators alike: -2(2a-1)/(a+2)(2a-1) + 3a(a+2)/(a+2)(2a-1) = -4a+2/(a+2)(2a+1) + 3a^2+6a/(a+2)(2a-1) What I want to know is if I can eliminate the a+2 for the first fraction, on both the numerator and the denominator?

In this problem: 5/12b + 15/36b^2 First I made a common denominator: 15b/36b^2 + 15/36b^2 Then I simplified the first fraction: 5/12b + 15/36b^2 Can I simplify the second fraction by 3b? If I can, what am I supposed to get?
