Algebra

I have one more question I need to ask about algebra, this one is a perform the indicated operation question.
4x 5x
  
x^29 x^2+4x+3
I am really confused on the +3 part, I don't know if my teacher made a typo or what, because without the  in that part it would be easily factorable.

oops it didn't write the question like i wanted it to, here I'll fix it
4x/x^29  5x/x^2+4x+3 
I also think the + is a typo error by your teacher. Assume it is +
Then you have
4x/[(x+3)(x3)]  5x/[(x+3)(x+1)]
= [1/(x+3)][4x(x+1)5x(x3)]/[(x+1)(x3)]
= [1/(x+3)][x^2+19x]/[(x+1)(x3)]
= x(x19)/[(x+1)(x3)(x+3)]
I don't guarantee I did that right. I created a common denominator, but it is still pretty messy.
