分解因式:10a(x-y)^2-5a(y-x)^3
分解因式:10a(x-y)^2-5a(y-x)^3

分解因式:10a(x-y)^2-5a(y-x)^3
10a(x-y)^2-5a(y-x)^3
=10a(x-y)^2+5a(x-y)^3
=5a(x-y)^2*[2+(x-y)]
=5a(x-y+2)(x-y)^2

原式=5a(x-y)^2(2+x-y)

10a(x-y)^2-5a(y-x)^3
=10a(x-y)^2+5a(x-y)^3
=(x-y)^2[10a+5a(x-y)]
=(x-y)^2(10a+5ax-5ay)
=5a(x-y)^2(2+x-y)

10a(x-y)^2-5a(y-x)^3 =10a(x-y)^2+5a(x-y)^3=5a[2(x-y)^2+(x-y)^3]=5a(x-y)^2[2+(x-y)]=5a(x-y)^2(2+x-y)

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