Homework Statement
(4a/a+4)+(a+2/2a)
Homework Equations
Just combine and then factor out
The Attempt at a Solution
It's actually fairly simple, but I'm having difficulty at the end.
/multiply each term by opposite denominator
4a(2a)/a+4(2a) + a+2(a+4)/2a(a+4)
/combine
4a(2a)+(a+2)(a+4) / a+4(2a)
=9a2+6a+8 / a+4(2a) ---- do I try to factor the numerator?
=a2+6a+72 / a+4(2a) ---- to this and keep going? There are no real roots.
=3a(3a+2)+8 / a+4(2a) ---- or do I factor the 9a2+6a, or possibly the 6a+8 and leave the 9a2?
I'd really appreciate some help with this one.
