Use long division to divide x^3+x^2-2x+14 by x+3

First, , and if we multiply by we get

Subtracting this from the numerator gives a remainder of

Next, , and if we multiply by we have

and subtracting this from the previous remainder, we end up with a new remainder of

Next, , and if we multiply by we get

Subtracting from the previous remainder, we get a new remainder of

which contains no more factors of , so we're done.

So,

i dont know sorry
