    math problem-simplify

    I can multiply this easily-but the problem says to simplify it. I have the answer and NO idea how to get there. Can someone help to simplify:

    (3x^2-2x^2-7)(8x^2-8x+7)

    Please show steps-I'm lost! Thanks!

    It was meant to be (3x^3-2x^2-7)(2x^2-8x+7) I think.

    Are you sure you typed it right? Is it (3x^2-2x-7)(8x^2-8x+7) or (3x^3-2x^2-7)(8x^2-8x+7)\;\;?

    Is this (3x^2-2x^2-7)(8x^2-8x+7) the right question in your book? If it is then

    = (3x^2-2x^2-7)(8x^2-8x+7)

    =(x^2-7)(8x^2-8x+7)

    now finish it.

    The answer in your book is wrong then.
