    Answer: f·g (x) = 12x³ - 6x² - 10x + 5

    fog (x) = 24x² - 24x + 1

    Step-by-step explanation:

    f (x) = 6x² - 5 g (x) = 2x - 1

    f·g (x) = (6x² - 5) (2x - 1)

    = 6x² (2x - 1) - 5 (2x - 1)

    = 12x³ - 6x² - 10x + 5

    fog (x) = f (2x-1)

    = 6 (2x - 1) ² - 5

    =6 (4x² - 4x + 1) - 5

    = 24x² - 25x + 6 - 5

    = 24x² - 25x + 1

    I wasn't sure if you wanted multiplication or composition so I solved both.
