wrong /o\

Standard exercise from my book.

You're not far behind what we do in class :P

We had shit like (x + 8)^2 where you're supposed to make it an equation without the "( )"

Lol hater thats the easyest part in math, btw I was lerning that when i wass 12 years so its not a big problem now.
The bracket thing is speshul though since you have the "^2" It get's messy :P I think the equation rule thing was "(a + b)^2 = a^2 + 2ab + b^2"..

Standard exercise from my book.

1. -7x+14=3x-1
-10x=-15
x=15/10=3/2
2.4x-4=6+6x
-2x=10
x=-5

x^2+16x+64
