xy + xy = 2xy
3x2+6xy+3y2= 3(x2+2xy+y2)= 3(x+y)2
That equals 2xy + 3y which factors to y(2x + 3)
2 (2x2 + 2x + xy + y ) it's 2 (2x + y)(x + 1) if you're doing A+
8-x2y 8-2xy 2xy-8
2xy + 6xy = 8xy
What is : 5xy- x2t + 2xy + 3x2t
The three terms are: -3xy2, 2xy and -4y3
1xy
15xy-2xy-7x+x=13xy-6x
xy + xy = 2xy
(2xy-4x)+ (8y-16)=2xy-4x+8y-16, which factors as 2(x+4)(y-2)
(x+y)2
( 2xy - 4x ) + ( 8y - 16)2 ( xy - 2x ) + 2 ( 4y - 8 ) Answer
They are four terms of an algebraic expression that can't be simplified
(x-y)2 is a square so (x-y)2 >= 0 expanding, x2 - 2xy + y2 >= 0 so x2 + y2 >= 2xy or 2xy <= x2 + y2
the difference between 2x2 +4xy-3 and x2-2xy-4 is?
