3x + 12
|-----------------
x - 4| 3x^2

3x^2 - 12x
------------------
12x
12x - 48

48

Don't understand how to divide x-4 into 3x^2

Click to expand...

\(\displaystyle \frac{3x^2}{x-4} \ = \ \frac{3x^2-12x + 12x - 48 + 48}{x-4} \ = \ 3x \ + \ 12 \ + \ \frac{48}{x-4}\)

You have shown the correct work.

I am not sure where you are stuck. If you don't feel comfortable with polynomial division - you probably are not ready for this class.
