Did you try to factor this, or did you use polynomial long division?

mendicant_bias · Answer

(?)

anonymous · Answer

I tried factoring. I am really bad at solving problems like this though

mendicant_bias · Answer

No problem! Did your teacher or does the problem you're working with specify a meth of solving it, or does it just let you do whatever? Is there a specific way you're supposed to be solving this?

anonymous · Answer

It does not specify any way of solving it, It does list choices though if that helps but other than that it isn't really helpful

mendicant_bias · Answer

Yeah, could you list the choices, too?

anonymous · Answer

a. x^2+5x-4
b.x^2+7x-9
c.x^2+3x-1
d.x^2+3x+1

if you don't know how to do long division or synthetic, you can do: (x+2) * EACH of the options. And then consider which one give you the polynomial x^3 +5x^2+5x-2, that is the answer.

Do you know how to do polynomial long division? If not, I can show you how. The correct answer is not the one you have.
