    10a² - 17a + 6

    Step-by-step explanation:

    Given

    (5a - 6) (2a - 1)

    Each term in the second factor is multiplied by each term in the first factor, that is

    5a (2a - 1) - 6 (2a - 1) ← distribute both parenthesis

    = 10a² - 5a - 12a + 6 ← collect like terms

    = 10a² - 17a + 6 ← in expanded form
