phan tich da thuc sau thanh nhan tu bang nhom hang tu x\(^2\) -(a+b).x+ab
ax-2x-a\(^2\) +2a
Phan tich cac da thuc thanh nhan tu:
x3- 2x2 - x + 2
x2 + 6x - y2 + 9
phan tich da thuc thang nhan tu:
a,\(x^3-2x^2+2x-1\)
Phan tich da da thuc thanh nhan phan tu
(x^2+x+1)(x^2+x+2)-12
phan tich da thuc thanh nhan tu :
a,(x-5)^2+(x-5)(x+5)-(5-x)(2x+1)
b,\(\left(3x-2\right)\left(4x-3\right)-\left(2-3x\right)\left(x-1\right)-2\left(3x-2\right)\left(x+1\right)\)
phan tich da thuc thanh nhan tu ;
\(3x^2-3y^2-2\left(x-y\right)^2\)
phan tich da thuc thanh nhan tu :
\(3x^2-3y^2-2\left(x-y\right)^2\)
phan tich cac da thuc:
x^2-2x+xy-2y
Phan tich thanh nhan tu:
a) x3 -x + 3x2y +3xy2 +y3 -y
b) 5x2 -10xy +5y2 -20z2
