Question

Find J(x) if

Answer 1

\(x^{3}+3x^{2}+x-2=(x+2)\times~J(x)\)

Answer 2

To double check your answer?
Well what did you end up with?

You applied polynomial long division or synthetic division, yes?

Answer 3

i got J(x)=\(x^{2}+x-1\)

Answer 4

i sub. ax^2+bx+c into J(x)
and compare both sides to find the values of a,b and c.

Answer 5

what is synthetic division?

Answer 6

Ah that's clever :)
Ya I prefer doing synthetic division myself.

Answer 7

Hmm it's a little hard to explain if you've never seen it before...
The numbers along the top row are the coefficients.

Answer 8

Either way, it looks like you got the correct answer which is great.
