因式分解x²-2xy-3x原式=x(x-2y-3)再问：这是最简的吗再答：对，只能分解到这个程度。
8（x平方-2y平方)-x(7x+y)+xy=8x平方-16y平方-7x平方-xy+xy=x平方-4y平方=(x-2y)(x+2y)手机提问的朋友在客户端右上角评价点【满意】即可.再问：太棒了！连我这
xy^2-4x=x(y+2)(y-2)-2a^2+4ab-2b^2=-(a-b)^2a^2(x-y)+b^2(y-x)=(x-y)(a+b)(a-b)(a^2+b^2)^2-4a^2b^2=(a+b)
xy²+2xy-x=x(y²+2y-1)=x(y²+2y+1-2)=x[(y+1)²-2]=x(y+1+√2)(y+1-√2)再问：太厉害啊，那再做多两题吧，也
x²-xy+xz-yz=x(x-y)+z(x-y)=(x+z)(x-y)若仍有疑问,欢迎追问!
x²-2xy+y²-2x+2y+1=(x-y)²-2(x-y)+1=(x-y-1)²-x^(n+1)+2x^n-x^(n-1)=-x^(n-1)*x^2+2x^
题目不清楚啊,那个是几次方啊?算了,我就按2次方做了啊2x^2+xy-6y^2=(2x-3y)(x+2y)6（x+y)^2-5(x+y)-1=[6(x+y)+1][(x+y)-1]=(6x+6y+1)
题目是不是x^2y-7xy+6yx^2y-7xy+6y=y(x^2-7x+6)=y(x-1)(x-6)
xy+2x+y+2=y(x+1)+2(x+1)=(x+1)(y+2)
因式分解xy²-2xy+x+2y-1解xy²-2xy-y²+x+2y-1=xy²-2xy+x-y²+2y-1=x(y²-2y+1)-(y&#
x^2y+xy^2=xy(x+y)
(x+y)(x-y)-x(y+1)-y(y+1)=(x+y)(x-y)-(x+y)(y+1)=(x+y)(x-2y-1)
-xy^2+2xy-x=-x(y^2-2y+1)=-x(y-1)^2如果本题有什么不明白可以追问,如果满意请点击“选为满意答案”
大胆地做!4x^3-xy^2=x(4x^2-y^2)=x(2x+y)(2x-y)记住：这种题都不会太难的,要大胆地去做它!先提公共的因式x,然后就可以用平方差公式了!
xy+y平方+x-y-2=xy+x+y^2-y-2=x(y+1)+(y+1)(y-2)=(y+1)(x+y-2)
-2xy-x²-y²=-(x²+2xy+y²)=-(x+y)²16(m-n)²-9(m+n)²=[4(m-n)+3(m+n)]*[
mn（x^2+y^2）+xy（m^2+n^2）=mnx^2+mny^2+m^2xy+n^2xy=(mnx^2+m^2xy)+(mny^2+n^2xy)=mx(nx+my)+ny(my+nx)=(mx+
y^3+xy^2+2xy+x^2-1=(x+y-1)(x+y^2+y+1)再问：烦写出过程再答：
-x^2+2xy-y^2=-（x²-2xy+y²)=-(x-y)²
xy-x-y+1=x(y-1)-(y-1)=(x-1)(y-1)(xy-x-y+1)^2=(x-1)^2(y-1)^2
