All six of them
4x^2+2xy-3y^2-2x^2+5xy-2y2Collect the like terms=2x^2+7xy-5y^2We cannot factorise it because the end term is a negative whilst the second-last term is positive.
It is: 7a/5xy

You need at least two terms to find a GCF.
(-5xy):(-xy)=
It is: 7a/5xy
x2 + 5xy - 18y2 can not be factored.
5xy+4=9

2(y - 3)(y - 10)
10x2y2 + 8xy2 - 210y2 = 2y2(5x2 + 4x - 105) = 2y2(5x2 + 25x - 21x - 105) = 2y2(x + 5)(5x - 21).
