Choose one answer.
a. 3(2x4 + 5x2 - 6x)
b. x(6x3 + 15x - 18)
c. 3x(2x3 + 5x - 6)
d. 3x(2x - 3)(x + 2)

Answer 1

What's your opinion?

Answer 2

a

Answer 3

Good

Answer 4

But you still can factor 1 more thing

Answer 5

To FACTOR completely, you just take out the greatest common factor, which in this case is a 3. You also take out an x, since all the terms have at least one x.

You took out a 3 and an x, so the correct answer is 3x(2x^3 + 5x - 6).

HOWEVER, if you want to solve the problem, you will need to find the possible rational roots and plug them in.
