    Product means multiplication

    (3a + 5) * (2a^2 + 4a - 2)

    You must multiply each factor in the first paren with each factor in the second:

    6a^3 + 12a^2 - 6a + 10a ^ 2 + 20a - 10

    Combine like terms:

    6a³ + 22a² + 14a - 10

    This is your answer

    (3a + 5) * (2a^2 + 4a - 2) =

    3a (2a^2 + 4a - 2) + 5 (2a^2 + 4a - 2) =

    6a^3 + 12a^2 - 6a + 10a^2 + 20a - 10 =

    6a^3 + 22a^2 + 14a - 10 <===
