Answer 1

Can you use synthetic division to divide

\[\Large \frac{x^4+4x+9}{x^3+12}\]

??

Answer 2

I don't think so since x has an exponent. Is that when you can't use synthetic division?

Answer 3

yes, you can only use synthetic division when you're dividing by something of the form x-k where k is some constant number.

Answer 4

so you can't use synthetic division to divide by x^3+12
