Subtract the sum of `3l-4m-7n^2a n d\ 2l+3m-4n^2` from the sum of `9l+2m-3n^2` and `-3l+m+4n^2dot`

Subtract the sum of 3l-4m-7n^(2) and 2l+3m-4n^(2) from the sum of 9l+2m-3n^(2) and -3l+m+4n^(2)

Subtract the sum of 10m - 8n + 6p^(2) "and" - 7m - 4n + 12p^(2) from the sum 2m - 4n + 6p^(2) "and" m-8n + 12p^(2) .

Subtract: 3l(l-4m+5n) om 4l(10n-3m+2l)

If m=- 4 , n=-2 then the value of m^3 - 3m^2 + 3m + 3n + 3n^2 + n^3 is

Add: 5m - 7n, 3n - 4m + 2, 2m - 3mm - 5
