Question

3n(n-4m+5p) - 4n(10p-3m+2n)

Answer 1

Answer:

$-5n^{2} - 25np$

Step-by-step explanation:

=> 3n [ n - 4m + 5p ] - 4n [ 10 p - 3m + 2n ]

=> [3n][n] + [3n] [-4m] + [3n][5p] + [-4n][10p] + [-4n][-3m] + [-4n][2n]

=> 3n^2 - 12mn + 15np - 40np + 12mn -8n^2

=> 3n^2 + 15np - 40np - 8n^2

{ In This Step -12mn And 12mn got cancelled }

=> -5n^2 - 25np

Answer 2

Step-by-step explanation:

5n

2

−25np

Step-by-step explanation:

=> 3n [ n - 4m + 5p ] - 4n [ 10 p - 3m + 2n ]

=> [3n][n] + [3n] [-4m] + [3n][5p] + [-4n][10p] + [-4n][-3m] + [-4n][2n]

=> 3n^2 - 12mn + 15np - 40np + 12mn -8n^2

=> 3n^2 + 15np - 40np - 8n^2

{ In This Step -12mn And 12mn got cancelled }

=> -5n^2 - 25np
