The x4 terms:
3x4 - 3x4
cancel out. The x2 terms:
(-4-2-2)x2 = -8x2 = answer C

best Answer is -8*2
Multiplication has higher precedence than addition and subtraction. so if u calculate the above expression, it turns out to be -16.

I really wish kids would stop posting retardedly simplistic homework that can't be explained without just giving you the answers. Ask your parents to help you. If they aren't able to figure those out then.... my god...

pay attention in class, get off the internet, and try and learn for youself, because the problems only get harder, and will be impossible if you don't learn the basics now
