(x+y)2
No, it equals -2xy. lrn2math
(2x2+4xy-3)-(x2-2xy-4)Answer: x2+6x+1
4x[squared]y
Only when X or Y = 0 That is because (x + y) squared = x^2 + 2xy + y^2 x^2 + 2xy + y^2 = x^2 + y^2 when x or y = 0
(x+y)2 = x2 + 2xy + y2
You can expand (x + y)2 into x2 + 2xy + y2
(x - y)2 = x2 - 2xy + y2
2(x - 1)(2x + y)
3x2+6xy+3y2= 3(x2+2xy+y2)= 3(x+y)2

Since 2xy is a factor of 2x2y, it is automatically the GCF.
