因式分解:10a(x-y)^2-5b(y-x)因式分解:10a(x-y)^2-5b(y-x)因式分解:10a(x-y)^2-5b(y-x)10a(x-y)^2-5b(y-x)=10a(x-y)^2+5

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

因式分解:10a(x-y)^2-5b(y-x)
10a(x-y)^2-5b(y-x)
=10a(x-y)^2+5b(x-y)
=(10ax-10ay+5b)(x-y)
=5(2ax-2ay+b)(x-y)

10a(x-y)^2-5b(y-x)
=5(x-y)[2(x-y)+b]
=5(x-y)(2x-2y+b)
