know :-

whenever in Question said substract any value from this ( any value ) then we have to subtract first value from those value which is written after from.

e.g=>substract 2 from 4 ;here 4 is written after from so,4-2=2

 = 4 {m}^{2}  - 3mn + 8 - ( -  {m}^{2}  + 5mn)

 =  > 4 {m}^{2}  - 3mn + 8 +  {m}^{2}  - 5mn

 =  > 4 {m}^{2}  +  {m}^{2}  - 3mn - 5mn + 8

 =  > 5 {m}^{2}  - 8mn + 8

 \bold{=  > 5 {m}^{2}  - 8(mn - 1)}
