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 $\displaystyle (3x^3-2x^2-7)(2x^2-8x+7)$ I think.

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

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

$\displaystyle = (3x^2-2x^2-7)(8x^2-8x+7)$

$\displaystyle =(x^2-7)(8x^2-8x+7)$

now finish it.

The answer in your book is wrong then. - Dec 6th 2008, 07:12 PMRobin Howardmath
