Ok I have to Distribute and Simplify...

2x(3x-24) + 4(2x+4+3y) - 2y(2x + 2y) - x(x-y)

Any help, much appriciated.

Where are you stuck in this

**simplification with parentheses**exercise? (It's a lot easier for us to "see" where you're having trouble if you show us what you've tried.)

You probably started with something like the following:

. . . . .$\displaystyle 2x(3x\, -\, 24)\, +\, 4(2x\, +\, 4\, +\, 3y)\, -\, 2y(2x\, +\, 2y)\, -\, x(x\, -\, y)$

. . . . .$\displaystyle 2x(3x)\, +\, 2x(-24)\, +\, 4(2x)\, +\, 4(4)\, +\, 4(3y)\, -\, 2y(2x)\, -\, 2y(2y)\, -\, x(x)\, -\, x(-y)$

. . . . .$\displaystyle 6x^2\, +\, (-48x)\, +\, 8x\, +\, 16\, +\, 12y\, -\, 4xy\, -\, 4y^2\, -\, x^2\, -\, (-xy)$

Where did you go from there?

Please be complete. Thank you! (Wink) - Apr 27th 2009, 05:27 AMelitescouter
To be honest I have no idea how to do this... That is why I am here. I have done problems like this before but never with x and y's so that is where I got confused.

This is what i got

$\displaystyle 5x^2\, -\, 48x\, +\, 16\, +\, 12y\, -\, 3xy\, -\, 4y^2\,$ - Apr 27th 2009, 05:54 AMmr fantastic
