phan tich da thuc sau thanh nhan tu:
a)(x-y+4)^2-(2x+3y-1)^2
Phan tich da thuc thanh nhan tu
x2-y2-3x+3y
phan tich da thuc thanh nhan tu: a,x^2-y^2-x+3y-2 b,x^3+y^3+6xy+x+y-10
Phan tich da thuc thanh nhan tu
x2-2xy+y2-3x+3y
Phan tich thanh nhan tu ( bang ki thuat bo sung hang dang thuc):
x^2-4xy-x+3y^2+3y
x^2+4xy+2x+3y^2+6y
6x^2+xy-7x-2y^2+7y-5
6a^2-ab-2b^2+a+4b
phân tich da thuc thanh nhan tu
1)x^3 +x^3y - x^3z - xyz
2)5xy^3 + 30x^2 z^2 - 6x^3 yz - 25y^2 z
3)25x^2-1/8x^2y^2
4)a^3x-ab+b-x
phan tich da thuc thanh nhan tu
1. x^3y^3 +x^2y^2+4
2. x^4+y^4+(x+y)^4
3.x^8+x+1
4.x^4+5x^3+10x-4
Bai 1 Phan tich da thuc thanh nhan tu
x^3 + 3x- 3xy- 3y
Bai 2 Tim x
( 2x - 1) ( 2x + 1) - 4 ( x ^2 +x ) = 16
cac bn lam on giup mink di ma
Phan tich thanh nhan tu bang ki thuat no sung hang dang thuc.
3x^2+8xy-3y^2
x^2 - x - xy - 2y^2+2y
