x3+xy-x2y2=x(x2+y-xy2)
If that's x2y and xy2, the GCF is xy.
-5xy2 + 12xy2 = (-5 + 12)xy2 = 7xy2
5x + 8xy + 10x + 3xy = 15x + 11xycombine like terms (the x's and the xy's)
Two terms of an expression
The GCF is xy
xy
If you mean: xy2/xy then it can be simplified to y
xy
xy
x3+xy-x2y2=x(x2+y-xy2)
If that's x2y and xy2, the GCF is xy.
They are terms in which a variable is raised to the same power (index) in both terms. So x2y and -27x2y are like terms but not xy2.
-5xy2 + 12xy2 = (-5 + 12)xy2 = 7xy2
