0 = 4y^3 -12y^2 -40y

0 = (4y^2 -12y -40)y

0 = (4y^2 + 8 y -20y -40) y

0 = ((4y - 20) (y+2))y

y=0 \/ y= 5 \/ y= -2

Answer:

D. Factoring trinomials

Step-by-step explanation:

The factoring trinomials method is the best way to factor the expression, since it is in the standard trinomial form ax² + bx + c

In this method, you can factor the expression by finding 2 factors of c that add up to b.

The expression is not in the simplest form, and difference of squares cannot be used because there are no perfect squares. Prime factorization is also not used for factoring expressions with variables.

So, D is the right answer.
