5a²b(x-y)的三次方-30ab²(y-x)²
5a²b(x-y)的三次方-30ab²(y-x)²
5a²b(x-y)的三次方-30ab²(y-x)²
5a²b(x-y)的三次方-30ab²(y-x)²
=5ab(x-y)²(ax-ay-6b)
5a²b(x-y)³-30ab²(y-x)²
=5ab(x-y)² × ( a(x-y)-6b )...................................提取公因式
=5ab(x-y)² × ( ax-ay-6b )
5a²b(x-y)^3-30ab²(y-x)²
=5a²b(x-y)^3-30ab²(x-y)²
=5ab(x-y)^2(ax-ay-6)
