phan tich da thuc thanh nhan tu
a) xy-y2+2x-2y
b) x2+2xy+y2-9
Phan tich da thuc x^2 + y^3 + 2x^2 -2cy + 2y^2 thanh nhan tu
phan tich da thuc thanh nhan tu
a)a^2x+a^2y-7x-7y
b)x^4-x^3-x+1
c)x.(x+1)^2+x.(x-5)-5.(x+1)^2
d)a^3-a^2x-ay+xy
phan tich da thuc thanh nhan tu :xy(x-y)-xz(x+z)+yz(2x+z-y)
Phan tich da thuc thanh nhan tu
x3 - 2x2 + x - xy2
6x2+xy-7x-2y2+7y-5 Phan tich da thuc thanh nhan tu
(x^2+x)^2+3(x^2+x)+2
x^2+2xy+y^2+2x+2y-15
phan tich da thuc thanh nhan tu
phan tich da thuc sau thanh nhan tu
2x^2-xy-y^2
phan tich da thuc thanh nhan tu (x^2+2x+3).(2x^2+2x+5)-8
