    if x+2 is a factor then x=-2 is a zero see for which polynomial when you plug in -2, gives you a result of 0

    I bet one of your choices is a tyoe-o and I think I know which one :)

    Look at your choices and you tell me which one looks like you have like terms.

    A) x^2 +4 B) x^2 -2x +1 C) 2x^2 -2x +1 D)x^3-6x^2+11x-6 E) 2x^2 + 10x^2 +10x -4 These are the choices you posted... Do you see a type-o? Look at the choice that has like terms.

    Is the last choice really suppose to have so many x^2 's?

    anyways I think it should be: A) x^2 +4 B) x^2 -2x +1 C) 2x^2 -2x +1 D)x^3-6x^2+11x-6 E) 2x^3 + 10x^2 +10x -4 now just evaluate each of those at x=-2 and see which outputs 0 and that will be your answer

    None of the polynomials have x+2 as a factor. Refer to the attached result from the Mathematica 9 program.

    this is why one of the choices is a type-o I think the type-o is in E because when you replace the x's with -2's in 2x^3+10x^2+10x-4 you get???

    I plugged -2 in all of them and E was the answer, and that's the correct answer there's no tyop

    but either or that's how you solve it right?

    yep you just look for which outputs 0 for x=-2 that is how you solve it (or I believe is the quickest way anyways)

    it isn't the only way just the quickest in my opinion
