4x-y2=2xy 2x ? y5 if its plus its 7 xy
-1
(x + 2)(y - 3)
xy - xy = 0
It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers (or expressions). Although it may not appear so, xyz + xy is only one expression.
It is an expression in the form of: xy+7
true
6
xy + xy = 2xy
7
x3y2 + 7x2y3 + 7xy - 2 + x2y3 + 8x3y2 - 3xy - 7 =9x3y2 + 8x2y3 + 4xy - 9 =xy ( 9x2y + 8xy2 + 4) - 9 =xy ( xy(9x + 8y) + 4) - 9 .This is still messy, but it's simpler than the octonomial in the question,and we can't see any more that can be done with it.
if you meant 2x²+y²-xy=21x=(±sqrt(-7 y^2+168)+y)/4y=(±sqrt(-7 x^2+84)+x)/2
xy + x + y + 1 = (x + 1)(y + 1).
2+2y+x+xy=(x+2)(y+1)
4x-y2=2xy 2x ? y5 if its plus its 7 xy
xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
xy plus 2x plus 4y plus 8 or (xy+2x) + (4y+8) or x(y+2) + 4(y+2) or (x+4)(y+2)
