✔ 最佳答案
5(3m-n)^2-(n-3m)=5(3m-n)^2+(3m-n)
=(3m-n)[5(3m-n)+1]
=(3m-n)(15m-5n+1)

5(3m-n)^2-(n-3m)
=5(3m-n)^2 - n + 3m
=5(3m-n)^2 +(3m - n )
=(3m - n )[5(3m -n) + 1]
=(3m -n)(15m - 5n + 1)
=5(3m-n)^2 - n + 3m
=5(3m-n)^2 +(3m - n )
=(3m - n )[5(3m -n) + 1]
=(3m -n)(15m - 5n + 1)

5(3m - n)^2 - (n - 3m)
= 5(3m - n)^2 + (3m - n)
= (3m - n) [5(3m - n) + 1]
= (3m - n) (15m - 5n + 1)
= 5(3m - n)^2 + (3m - n)
= (3m - n) [5(3m - n) + 1]
= (3m - n) (15m - 5n + 1)

5(3m-n)^2-(n-3m)
= 5(3m-n)^2 - n + 3m
=5(3m-n)^2+ 3m - n
=5(3m-n)^2 +(3m - n )
=(3m - n )(5(3m -n) + 1)
=(3m -n)(15m - 5n + 1)
= 5(3m-n)^2 - n + 3m
=5(3m-n)^2+ 3m - n
=5(3m-n)^2 +(3m - n )
=(3m - n )(5(3m -n) + 1)
=(3m -n)(15m - 5n + 1)

5(3m-n)^2-(n-3m)
=5(3m-n)^2+(3m-n)
=(3m-n) (5(3m-n)+1)
=(3m-n) (8m-5n+1)
=5(3m-n)^2+(3m-n)
=(3m-n) (5(3m-n)+1)
=(3m-n) (8m-5n+1)

5(3m-n)^2-(n-3m)
=5(3m-n)(3m-n)-(n-3m)
=5(3m-n)(3m-n)+(3m-n)
=5(3m-n)(3m-n+1)
=5(3m-n)(3m-n)-(n-3m)
=5(3m-n)(3m-n)+(3m-n)
=5(3m-n)(3m-n+1)

5(3m-n)^2-(n-3m),,
= 5(3m-n)^2+(3m-n)
=(3m-n)(15m-5n+1)
= 5(3m-n)^2+(3m-n)
=(3m-n)(15m-5n+1)
