    = 16x^3 – 30x^2 – 73x + 30

    I used the long multiplication method, which is this:

    1. Put the smaller expression under the longer one, as if you were multiplying like this(but with the expressions):

    10
    x 1
    —-

    Solve the operations as if you would the multiplication operation above, following all variable rules and do not worry about carrying over. What this should look like is:

    2x^2 – 5x – 6
    8x – 5
    ——————
    10x^2 – 25x + 30
    + 16x^2 – 40x^2 – 48x+ 0
    ————————————-

    After that, add.
