6y-18+xy-3x its impossible to do anything to it
x = 6y over (y-6)
5x + 8xy + 10x + 3xy = 15x + 11xycombine like terms (the x's and the xy's)
y(z+x) + 4(x+z)
(b - x)(ab - xy)
xy - 10x + 6y - 60 = x(y - 10) + 6(y - 10) = (y - 10)(x + 6)
6y-18+xy-3x its impossible to do anything to it
(y - 3)(x + 2y)
x = 6y over (y-6)
5x + 8xy + 10x + 3xy = 15x + 11xycombine like terms (the x's and the xy's)
x(y-10)+6(y-10) ^^^that's the first step, then: the x and 6 pair together, and one of the (y-10) leaves the expression so it becomes: (x+6)(y-10) this is referred to as Factoring by Grouping
2+2y+x+xy=(x+2)(y+1)
Using real numbers, you cannot.
x2y + axy + abx + a2b Factor by grouping. xy(x + a) + ab(x + a) (xy + ab)(x + a)
Divide by 'x'; x2+xy/x = x(x+y)
(x-y) + (xy - 1) = (x - 1)(y + 1)
(x + 2)(y + 1)
