QUESTION !!! :P

Hey everyone I've got a little question

There's is this one question i don't get maybe on of you can help me :
     a-2            a² -4a  -5        1  
2a³+12a²  =    2a³+12a²   +  2a

my problem is the 2a³ and a² is both in there so how do work with both of them on the same time ?

Thanks :)

  1. The denominator is 2a³+12a²
    You have difficulty in solving the last part 1/2a
    Then you will factor 2a out of denominator.
    You should get (a²+6)
    Answer is a=1& a=-3/2
    Hope that will help.
