因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
5x^3y*(-3y)^2+(-6xy)^2*(-xy)+xy^3*(-4x^2)
1、(-7x^y)(2x^y-3xy^3+xy) 2、((x-y)^6)/((y-x)^3)/(x-y)
化简:x-y/x+3y÷x^-y^2/x^2+6xy+9y^2-(xy/x+y)
诺x+y=6,xy=4 求(5x-4y-3xy)-(8x-y+2xy)
(x-2xy)*(-xy+2y*y)-(3x*x-2xy)(x-9xy+6y*y)答案应为-2x-x*x-3x,
x^2-xy-6y^2+3xy+y+2
因式分解 (3x+2y)-(x-y)² x²-xy+3y-3x 2x²+xy-y²-4x+5y-6
3y/x*x-y*y+x/x*x-2xy+y*y+6y*y/x*x*x-x*x*y-xy*y+y*y*y等于多少?
因式分解 求过程 x-xy+3y-3x 2x+xy-y-4x+5y-6
3x平方-5x平方y-{2x平方y+6xy平方-[2xy平方-3x平方y+(3x平方y-4xy平方】}
图解(x+2y)(x+3y)=x平方+5xy+6y平方
4xy-[(x²+5xy-y²)-(3xy-1/2y)]x=3,y=-6
√x(√x+2√y)=√y(6√x+5√y,求x-3√xy+2y/x+√xy-6y
∫x(∫x+2∫y)=∫y(6∫x+5∫y),求:(x+∫xy-y)/(2x+∫xy+3y)
x^2+xy-6y^2-3x+6y
2x^2+3xy+y^2+x-y-6
2X^+XY-Y^-4X+5Y-6
