Thread: Simplify Equation

I am unable to come up with the answer to the key for this problem. Can someone give it a try?

(4x^2+x-6)/(x^2+3x+2)-3x/(x+1)+5/(x+2)

Thanks in advance!

Dear sprivitor,





By simplification we would get,







Hope this helps.

Did you realise that x^2+3x+2 = (x+1)(x+2) ?

Thank you. I now see my problem was with a simple negative sign.

-3X/(X+1) + 5 / (X+2)

I made the WRONG assumption that this equals

-[3X/(X+1) + 5 / (X+2)]

it is equal to

-[3X/(X+1) - 5 / (X+2)]
