Answer 1

What do you know about Synthetic Division?

Answer 2

Not too much

Answer 3

EVER seen it?

Answer 4

You could also use polynomial division but synthetic is easier (less baggage in the calculation)

Answer 5

No @tkhunny

Answer 6

Yeah, that would be way easier. All is not lost, however. We can still just use the Remainder Theorem. First, we must establish that the remainder will look like this, \(\dfrac{Something}{x-3}\). Agreed?
