____ r + 3
r+9)r^2+12r+36
_____ r^2+9r
_______ 3r+36
________3r+27
_____________9

Answer: r+3+9/r+9 OR r+3 R (remainder) 9

Basicly, how many times will r (of r+9) go into r^2, it should be r right? Then multiply r by r+9, you get r^2+9r, subtract it from r^2+12r, you get 3r+36...and so on.

I would like someone to check my work for me though, I haven't done this for quite a while already.
