x三次方-2x平方y+xy平方4a平方-2a-b平方-b3y平方+11y+102a(x平方+1)平方-8ax平方

x^3-2x^2*y+xy^2
=x(x^2-2xy+y^2)
=x(x-y)^2
4a^2-2a-b^2-b
=(4a^2-b^2)-(2a+b)
=(2a+b)(2a-b)-(2a+b)
=(2a+b)(2a-b-1)
3y^2+11y+10
=(y+2)(3y+5) -----这个是十字交叉法做
2a(x^2+1)^2-8ax^2
=2a[(x^2+1)^2-(2x)^2]
=2a(x^2+1+2x)(x^2+1-2x)
=2a(x+1)^2(x-1)^2
晕死。慢了一步。%>_

x^3-2x^2 y+x y^2=x(x^2-2xy+y^2)=x(x-y)^2
(2a-b)(2a+b+1)
(3y+5)(y+2)
2a(x+1)^2(x-1)^2
上面那位快一点点，呵呵

x^3-2x^2y+xy^2=x(x^2-2xy+y^2)=x(x-y)^24a^2-2a-b^2-b=4a^2-b^2-2a-b=(2a+b)(2a-b)-(2a+b)=(2a+b)(2a-b-1)3y^2+11y+10=(y+2)(3y+5)2a(x^2+1)^2-8ax^2=2a[(x^2+1)^2-4x^2]=2a[(x^2+1+2x)(x^2+1-2x)]=2a(x+1)^2(x-1)^...
