ok, I know how to do synthetic division now thanks to satellite73, but I have a question on one of my problems.

Question

$$(x ^{4}+x ^{2}-6)\div(x ^{2}+3)$$

what do I do with the exponent in x^2+3??

@taylorvengam please see the picture...

anonymous · Answer

I have to use synthetic division @paki

whpalmer4 · Answer

you could make a substitution:
$$u = x^2$$

which turns your problem into $$\frac{u^2+u-6}{u+3}$$which you can tackle with synthetic division.  Then undo the substitution once you've done the division.

@paki did you not understand that she's supposed to use synthetic division for this problem?

@whpalmer4  so which method i used here....?

whpalmer4 · Answer

@paki That's factoring, not synthetic division.  Synthetic division only works with linear divisors (no exponents other than 1)
