因式分解x2+y2-xy-x-y+1
2x2+xy-3y2+x+4y-1因式分解
因式分解 x2+xy-2y2-x+7y-6
x2-xy-2y2-x+5y-2因式分解
因式分解 x2(x+1)-y(xy+x)
因式分解:x3+(y-1)x2-2xy-y2
阅读下面例题:把多项式x2-2xy+y2-2x+2y+1因式分解.
因式分解x2-y2-z2-2yz+1-2x x2-6xy-10x+30 y+25
25(x2+ 2xy +y2)-9(x2-2xy+y2)因式分解.x2,y2是x平方,y平方的意思.2xy就是2xy.快
因式分解x2+y-xy-x
因式分解:x2-xy-y2 X平方减XY减Y平方.
