Have you done long division with polynomials before ?

Yeah, you don't need to longdivide to do it. Just factor the larger polynomial by grouping. So if you group the first two terms as \[(2x^{3}x^{2})+(24x+12)\] now you can factor out \[x^{2}\] from the first group, and factor out 12 in the second group. You get \[x^{2}(2x1)12(2x1)\] Now because \[2x1\] is in both terms, then you can factor this out of each term and get \[(2x1)(x^{2}12)\] Therefore \[(2x^{3}x^{2}24x+12)\div (2x1) = \frac{2x^{3}x^{2}24x+12}{2x1}=\frac{(2x1)(x^{2}12)}{2x1}\] From this you can see that you can cancel a factor of \[2x1\] Therefore this becomes just \[x^{2}12\] which is the correct answer. I have no idea what the rest of the questions are asking, but you should try to do them yourself now that you have this much anyway.

What @AddemF described is called factoring by grouping. This allows you to factor the numerator and cancel any terms from the denominator that are common with them. I thought from the question you asked to divide but this simplifies to the same thing. Whichever method works best for you @jroop!
