Do you know how to combine like terms?
how do u mean... solve?
like factorise? find roots? find derivatives?
I'm trying to figure it out but my brain stopped working.. sorry .-.
what are you being asked to solve for?
it might help to know what subject are you studying
look can ll me if I did right? xy-4x+2y-8 x(y-4)+2(y-4) (y-4)(x+2)
if your being asked to factor then yes , thats right
FOIL first = x * y = xy = correct so far last = a * b = -8 sooo... outer and inner = ay + bx (x+a)(y+b) (x+2)(y-4) proof first = x * y = xy = correct so far last = a * b = 2 * -4 = -8 = correct outer and inner = ay + bx = 2y - 4x = correct
