(3x+2y)(4x-3y)-5xy要分解因式
(3x+2y)(4x-3y)-5xy
要分解因式
(3x+2y)(4x-3y)-5xy要分解因式
(3x+2y)(4x-3y)-5xy
=12x^2-9xy+8xy-6y^2-5xy
=12x^2-6xy-6y^2
=6(2x^2-xy-y^2)
=6(2x+y)(x-y)
因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
3x^2+5xy-2y^2+x+9y-4分解因式怎么分?
3x^2+5xy-2y^2+x+9y-4分解因式怎么分?
化简:3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
x²-y²+5x+3y+4(x+y-2xy)(x+y-z)+(xy-1)²
x^3y(-4y)^2+(-7xy)^2*(-xy)-5xy^3*(-3x)^2
5x^3y*(-3y)^2+(-6xy)^2*(-xy)+xy^3*(-4x^2)
7x^2y-[xy+4(xy^2+1/8xy)-3x^2y]答对给分
已知x-y=3xy,求5x+2xy-5y/x-4xy-y的值
诺x+y=6,xy=4 求(5x-4y-3xy)-(8x-y+2xy)
计算(x^8-x^7y+x^5y^3-x^4y^4+x^3y^5-x^y^7+y^8)(x^2+xy+y^2)
若x-y=4,xy=1,则(2x+y-2xy)-(3x+2y+xy)-(4xy+3y-5x)=
(-2xy+2x+5y)-(3xy+2y-2x)-(x+4y+xy)其中x-y=4xy=-1
求(3x^+y^-5xy)-【2x^-(-4xy-y^+7x^)】=?
求(3x^+y^-5xy)-【2x^-(-4xy-y^+7x^)】=?
因式分解 (3x+2y)-(x-y)² x²-xy+3y-3x 2x²+xy-y²-4x+5y-6
x平方-4xy+4y平方-2x+4y-3分组分解法
