Question 11838: 3a-1/a^2+4a+4 - 3/a^2+2a = 3/a
this is a problem from my homework that is asking me to simply solve the equation. i don't know where or how to start to get the correct answer of
a = -9/8
any help with this would be greatly appreciated.
thanks

i am assuming you mean ? If so, then...

So, just fractions now...i will multiply both sides, that is ALL terms by the same thing, namely a(a+2)(a+2), as this is the lowest common factor of all three fractions. Doing this does not "change" the equation, it just "scales" it up a bit.

By multiplying each term by the above, we can then cancel the fractions to leave:

or 16a = -18
--> a = -18/16
--> a = -9/8
