3x2+6xy+3y2= 3(x2+2xy+y2)= 3(x+y)2
3x2y - 4xy + 4x
2y + 2xy' + 4y + 4xy' = 0 6y + 6xy' = 0 y' = -y/x
No, it equals -2xy. lrn2math
Totally pointless
6xy +12y = 6y (x+2)
What is : 5xy- x2t + 2xy + 3x2t
The three terms are: -3xy2, 2xy and -4y3
By factorisation: x2 + 6xy - 27y2 = (x + 9y)(x - 3y).
2x2 + 6xy = 2x (x + 3y)
