Question

Which of the following best describes the relationship between (x + 1) and the polynomial -3x3 - 2x2 + 1?

A. (x + 1) is a factor.
B. (x + 1) is not a factor.
C. It is impossible to tell whether (x + 1) is a factor.

Answer 1

im guessing B.

Answer 3

Hey

Answer 4

X+1 is a factor

Answer 5

First I would try expressing the polynomial in terms of three products

Answer 6

ok

Answer 7

-3x3-3x2+x2+1
I expanded -2x2=-3x2+x2

Answer 8

(x+1)*(x + a)* ( x+ b )

Answer 9

Then
-3x2(x+1) +x^2+1
Sorry wait it's not a factor because we can't express x2+1 in form of (x+1)

Answer 10

now since 3x^3 is one of your final terms you know 3x must be one if it's factors

Answer 11

(3x+1) even

Answer 12

@Roronoa it's not a factor

Answer 13

So if (3x+1) must be a factor the other two factors must be the product (x^2-x-1) to get our terms right?

Answer 14

(x^2-x-1) can not be factored by x+1, so it should be obvious, does that make sense to you?
