Answer:

(2y - 5) (3y^2 - 4)

Step-by-step explanation:

Group and factor by using the Greatest Common Factor (GCF).

6y^3 - 15y^2 - 8y + 20

Simply multiply the terms inside the first pair of parenthesis, by the terms in the second pair of parenthesis.

2y x 3y^2 = 6y^3

2y x (-4) = 8y

-5 x 3y^2 = 15y^2

-5 x (-4) = 20

6y^3 - 8y -15y^2 + 20

Now, simply simplify the problem!

(2y - 5) (3y^2 - 4)
