Assuming that im correct,im not all that good at algebra but ill give it a shot: 1 X on it's own equals 1,therefore 3x = 4,So 4 +2 equals 6. and X + 4 would equal 5,So 6 + 5 equals 11 __________________ __________________ Desktop:BitFenix Survivor~Gigabyte GA-P67A-UD3R~ i7 2600K @ 4hz~AMD 6870 1GB~12gb Team Elite DDR3 1333~3xWD In RAID5~W7 Ult Laptop:Alienware M11x~ i7-2637M 1.7GHz~16GB 1333MHz DDR3~GeForce GT 540M~W7 Ult

The answer is 3x^2 + 14x + 8 though, as root said, you use FOIL. __________________ C2D E6600 | 4GB DDR2-800 | 9800GTX+ | Asus P5B-E | 150GB Raptor | 320GB 7200.10 | 750W Xigmatek PSU

Wait till you get to factoring, which takes some trial and error for a while. I've gotten used to it so I just do by head =]
