Question

Which of the following is a factor of 2x3 – 2

Answer 1

you can factor out a monomial from that expression... you haven't really provided any choices for us, however

Answer 2

a.x2 + 2x + 1
b.x + 1
c.x2 + x + 1
d.None of the above

Answer 3

2(x-1) (X^2+X+1)

Answer 4

C

Answer 5

okay.
first, we can factor out that monomial, 2.

2(x^3 - 1)
That's now a difference of cubes, so we can factor it using this:
\[ a^3 - b^3 = (a - b)(a^2 + ab + b^2) \]
