    The factors are (3g+4) (2g^2-5) ...

    Step-by-step explanation:

    The expression is:

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

    Make a group of the first two terms and last two terms:

    (6g^3 + 8g^2) - (15g + 20)

    Now factor out the common from each group:

    2g^2 (3g+4) - 5 (3g+4)

    (3g+4) (2g^2-5)

    Therefore the factors are (3g+4) (2g^2-5) ...

    (3g+4) (2g^2-5)

    Step-by-step explanation:

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

    Lets factor by grouping

    Taking a 2 g^2 out of the first two terms and - 5 out of the last two terms

    2g^2 (3g+4) - 5 (3g+4)

    Factoring out (3g+4)

    (3g+4) (2g^2-5)
