Since both are equal to 0, they are equal.
If the expressions were not set equal to 0,
B - A = x^2 + 22x - 12
A = (x - 8)(x + 4)
for B-A to be 0,
x = -11 ± √(121 + 48)
x = -11 ± √(169) = -11 x = -11 ± 13 = -24,2, so for
x < -24, A < B
-24 < x < 2, B < A
x >2, A < B

combine like words interior the brakets. (x2 + 4x - 7) - (2x2 + 3x -3) is going right down to (6x - 7) .- (7x - 3) and from there you could not do something interior the brakets so they dissappear 6x - 7 - 7x - 3 and returned, combine like words (-1x - 10) is your answer. ((btw, i'm assuming 2x2 is calling what's two circumstances 2x. So i presumed 4x if so))

ok, there isn't any need to work the question out since in the question states that both A and B equal 0. therfore both are equal

Well, since the question states that both equations are equal to 0, I'd guess they're equal.

A if you mean the value of x in the problem A, its more than 2, which x in B is
