3x^2y^2—5x^2y+x^5—6的多项式的项3x^2 y^2—5x^2 y+x^5—6
3x^2y^2—5x^2y+x^5—6的多项式的项
3x^2 y^2—5x^2 y+x^5—6
3x^2y^2—5x^2y+x^5—6的多项式的项3x^2 y^2—5x^2 y+x^5—6
此多项式是五次四项式.项分别是3x^2y^2,-5x^2y,x^5和-6
若x+y分之x-y=3,求式子x+y分之5(x-y)—2(x-y)分之x+y的值
若x-y分之x+y=3,求式子x+y分之5(x-y)—2(x-y)分之x+y的值
[(x+2y)(x-2y)-(2x-y)²+(3x-y(2x-5y)]/(-x)的解答
[2(x-y)^5-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2[2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2
1.20y(2y-x)²与5x(x-2y)平方的公因式是—— 2.分解因式(x+y)(x-y)-(x+y)²
2(2x+3y)(3x+2y)-(6x-y)(2x-5y)
x+y/2+x-y/6=5 2(x+y)-3(x-y)=-2
—2x+5(x+2y)—(x—3y) 3x+2(y-x)-(-x-4y) (x-2y)-(y-3—2x+5(x+2y)—(x—3y) 3x+2(y-x)-(-x-4y)(x-2y)-(y-3x)
因式分解x次方-y次方+5x-y+6【x-y+2】【x+y+3】
6(x-y)-2(x+y)=14 3(x-y)+(x+y)=5
化简:5(x-y)+2(x+y)-3(x-y)
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
(2x-3y)-(5x-y)
(2X-3y)-(5x-y)
(2x-5y)(3x+y)
因式分解(x-2y)(x-3y)+(x-4y)(x-5y)+(x-3y)(x-5y)+(x-2y)(x-4y)
(2x+y)²+(x+3y)(x-3y)-x(5x+8y)因式分解
(x—y)的2次方×(x—y)的5次方×(y-x)=()
