thank you!

do you know how to divide synthetically?
that is the easiest way to divide a polynomial by something of the form (x-a)

anonymous · Answer

or you can substitute x =-3 in the equation

turingtest · Answer

but that won't tell you the quotient, just whether it is a root or not.

anonymous · Answer

yeah sorry. synthetic division is the easiest way though.

I say you should learn synthetic division either way, the last three problems you posted could be solved that way. http://www.purplemath.com/modules/synthdiv.htm www.youtube.com/watch?v=bZoMz1Cy1T4
