\underline{\Large\mathbf{Question}}

Subtract the sum of  \bf 8m - 7n + 6{p}^{2} and  \bf - 3m - 4n - {p}^{2} from the sum of  \bf 2m + 4n - 3{p}^{2} and  \bf - m - n - {p}^{2}


\underline{\underline{\huge\mathfrak{Solution}}}

Let us first add the equations,

Sum of  \bf 8m - 7n + 6{p}^{2} and  \bf - 3m - 4n - {p}^{2}

(8m - 7n + 6 {p}^{2} ) + ( - 3m - 4n -  {p}^{2} ) \\  \\  =  8m - 7n - 6 {p}^{2}  - 3m - 4n -  {p}^{2}  \\  \\ =  8m - 3m - 7n - 4n - 6 {p}^{2}  -  {p}^{2}  \\  \\  \bf = 5m - 11n - 7 {p}^{2}

Sum of  \bf 2m + 4n - 3{p}^{2} and  \bf - m - n - {p}^{2}

(2m + 4n - 3 {p}^{2} ) + ( - m - n -  {p}^{2} ) \\  \\  = 2m + 4n - 3 {p}^{2}  - m - n -  {p}^{2}  \\  \\  = 2m - m + 4n - n - 3 {p}^{2}  -  {p}^{2}  \\  \\   \bf = m + 3n - 4{p}^{2}

Now,

Subtracting  \bf 5m  - 11n - 7{p}^{2} from  \bf m + 3n - 4{p}^{2}

(m + 3n - 4 {p}^{2} ) - (5m - 11n - 7 {p}^{2} ) \\  \\ m + 3n - 4 {p}^{2}  - 5m + 11n + 7 {p}^{2}  \\  \\ m - 5m + 3n + 11n - 4 {p}^{2}  + 7 {p}^{2}  \\  \\  \bf  - 4m + 14n + 3 {p}^{2}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: or  \\ \bf 3 {p}^{2}  - 4m + 14n

If any doubt, please ask! ;)
