5X² 6XY-8X²因式分解还有7X²+13X-2
因式分解3x^2-6xy+x
(x-2xy)*(-xy+2y*y)-(3x*x-2xy)(x-9xy+6y*y)答案应为-2x-x*x-3x,
-3(2x^2-xy)+4(x^2+xy-6)
3x-2xy-8-2x+6xy-x²+6、-x²+2xy-y²-3x²-2xy+2y²合并同类项
4(x²+xy-6)-3(2x²-xy)
-3(2x²-xy)+4(x²+xy-6)
3x-2xy-8-2x+6xy-x的平方+6
3xy(x^2y-xy^2+xy)-xy^2(2x^2-6xy+2x)过程
因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
x^2+xy-6y^2+x+13y-6
[ 2x-6y][8-9xy]÷xy等于?
xy-2x+6y-12 xy+8
诺x+y=6,xy=4 求(5x-4y-3xy)-(8x-y+2xy)
因式分解:3x^2y+6xy-4x-8
因式分解 3x^2-6xy-4x+8y
1 (X-1)(x+2)(X-3)(X+4)+242 X方+XY-6Y方+X+13Y-6
因式分解x(x+1)(x^2+5x+6)-8 x^ 2+5xy+x+3y+2y^2
