    i got 1,281

    Right.

  • math -

    Could be a problem here ....

    The way you said it according to the order of operation :
    2ab^2 - cd
    = 2(9)(2^2) - 5(3)
    = 72 - 15
    = 57

    The way it was interpreted:

    (2ab)^2 - cd
    = (2(9)(2))^2 - 5(3)
    = 36^2 - 15
    = 1281

    Kahlil said that using the equation (a + b)2 = a2 + 2ab + b2, he can find a similar equation for (a - b)2. Examine his argument. (a - b)2 = [a + (-b)]2 = a2 + 2a(-b) + (-b)2 = a2 – 2ab + b2
