Question

How can the polynomial 6d^4 + 9d^3 – 12d^2 be factored?

a.) 3d^2(2d^2 + 3d – 4)
b.) 3d^2(3d^2 + 6d – 9)
c.) 3d(d3 + 3d^2 – 4)
d.) 6d^2(d^2 + 3d^3 – 6)

Answer 1

Well, you want the common factor outside of the parenthesis which is 3d

Answer 2

Think of what you can pull out, all terms have a d^(2) and a 3 in common right?

Answer 3

When you multiply polynomials, you add them together.
So...
3d^2(2d^2) becomes 6d^2+2, which is 6d^4
