    (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)
