=(a+2b)^3(a+b)
1 phan tich da thuc thanh nhan tu
a) 4x^2 - 49
b) a^2 -2a -b^2 -2b
phan tich da thuc:(a^2+b^2-c^2)^2-4a^2b^2 thanh nhan tu
phan tich da thuc thanh nhan tu
4a^2b^2-(a^2+b^2-c^2)^2
a^3(b-c)+ b^3(c-a)+c^3(a-b) phan tich da thuc thanh nhan tu
phan tich cac da thuc sau thanh nhan tu
a, (x-y)3 - (z-y)3 - (x-z)3
b, (2016x-2015)3 + (2014-2013x)3 + ( 1-3x)3
c, (2a+b+c)3 - (a-b+2c)3 - (a+2b-c)3
phan tich da thuc thanh nhan tu a(b^3-c^3)+b(c^3-a^3)+c(a^3-b^3)
PHAN TICH DA THUC THANH NHAN TU
B= X^3+Y^3+Z^3-3XYZ
phan tich da thuc thanh nhan tu
\(\left(\text{a}+b+c\right)^3-\text{a}^3-b^3-c^3\)
phan tich da thuc thanh nhan tu a(b^2+c^2)+b(c^2+a^2)+c(a^2+b^2)-2abc-a^3-b^3-c^3.
