opps the first ha
(2x - 3)(x + 4) = (2x)*(x) + (2x)*(4) + (-1)*(3)*(x) + (-1)*(3)*(4) ^ that results in 2 x^2 s ^ that results in 2 by 4 of x's ^ results in 3 negative x's ^ results in 3 by 4 of -1's
ooh, got it...sort of..can you help with the other questions please

ok, so it has to be B...right?

ok thank you, Appreciate it ^_^
