因式分解:-m2n×(x-y)的n次方+mn2×(x-y)的n+1次方因式分解:-m2n×(x-y)的n次方+mn2×(x-y)的n+1次方因式分解:-m2n×(x-y)的n次方+mn2×(x-y)的

因式分解:-m2n × (x-y)的n次方+mn2 × (x-y)的n+1次方
因式分解:-m2n × (x-y)的n次方+mn2 × (x-y)的n+1次方

因式分解:-m2n × (x-y)的n次方+mn2 × (x-y)的n+1次方
-m^2n × (x-y)^n+mn^2 × (x-y)^(n+1)
= mn^2 × (x-y)^(n+1)-m^2n × (x-y)^n
= mn^2 × (x-y)^n×(x-y)-m^2n × (x-y)^n
=mn(x-y)^n[n(x-y)-m]
=mn(x-y)^n([nx-ny-m)

=-mn(x-y)的n次方(m-nx+ny)
