因式分解:5a^2b(x-y)^2-10ab^2(y-x)^3因式分解:5a^2b(x-y)^2-10ab^2(y-x)^3因式分解:5a^2b(x-y)^2-10ab^2(y-x)^35a^2b(x

因式分解:5a^2b(x-y)^2-10ab^2(y-x)^3
因式分解:5a^2b(x-y)^2-10ab^2(y-x)^3

因式分解:5a^2b(x-y)^2-10ab^2(y-x)^3
5a^2b(x-y)^2-10ab^2(y-x)^3
=5ab(x-y)^2[a-2b(y-x)]
=5ab(x-y)^2(a-2by+2bx)

5a"b( x - y )" - 10ab"( y - x )"'
= 5a"b( x - y )" + 10ab"( x - y )"'
= 5ab( x - y )"[ a + 2b( x - y ) ]
= 5ab( x - y )"( a + 2bx -2by )
