can't simplyfy but you can expand:
1. 40x^2 + 107x + 63
2. -63x^2 -25x +72
3. 81x^2 -144x + 64
4.24x^2 -82x + 63
5. -15x^2 + 22x - 8
6. 20x^2 + 14x - 24

simplyfy: 1.(7+8x) (9+5x) 2.(9+7x) (8-9x) 3.(8-9x) (3x+5x) 4.(9-4x) (7-6x) 5.(3x-2) (4-5x) 6. 2(5x-4) (2x+3)?

you must multiply all the numbers by all the others. we used to have a smiley face to represent it in my algebra class.
1. you must multiply first 7x9, then 8xX5x, then 7X5x, and then finally 8xX9.
7x9=63
8xX5x=40x^2
7X5x=35x
8xX9=72x
now you add all those that are alike, right now your exquation looks like this on paper:
63+40x^2+35x+72x
adding everything that is alike now looks like this
63+107x+40x^2
you cant add if the variables (fancy word for letter) if theyre not exactly alike. so square roots cant be added, unless theyre simplified. i cant remember how to do that, sorry! those without variables are in the front of the equation, it cant be simplified any farther, then its just in alphabetical and numerical order, but some teachers dont care. good luck! i hope this is enough information to get you working on it!

First off, do your own homework. If you honestly think anyone is going to sit here and do your homework, you are stupid.
Secondly, all you have to do is multiply the two, then combine like terms!
Third, wouldn't be easier just to do it instead of typing it all out!
LEARN TO DO YOUR OWN HOMEWORK!! IF YOU DON'T UNDERSTAND IT, ASK YOUR TEACHER FOR HELP!

Wouldn't it be easier to do your own homework than to type it all out here so that we can do it for you?
There's an added bonus to doing your own homework too... come test time, you won't have to study very hard because you've already done it yourself.
