    2a²-2

    Step-by-step explanation:

    (a-1) (2a+2)

    a (2a+2) - 1 (2a+2)

    2a²+2a-2a-2

    2a²-2

    Multiply each term in the first set of parenthesis by each term in the second set, then simply by combining like terms:

    (a-1) (2a+2)

    a*2a = 2a^2

    a*2 = 2a

    -1*2a = - 2a

    -1*2 = - 2

    Now combine:

    2a^2 + 2a - 2a - 2

    = 2a^2 - 2
