Question

Use synthetic division to find P(-3) for P(x)=x^4-2x^3-4x+4


the answer I got is x^2-5x+11 r-29

and I'm pretty sure that's wrong. Can someone help me?

Answer 1

You shouldn't get a polynomial result...

Here is a guide to it:

Answer 2

Basically if you are confident that the remainder is \(-29\), then \(P(-3)=-29\).

Answer 3

thats what I meant, the answer was -29, thats what I needed help with. I know how to write the answer, I needed to know if it was the right answer...
