Answer:

Answer of this term is,

 =  - 3 {m}^{3}  + 3{m}^{2}  + 3m - 8x  + 7

Step-by-step explanation:

Question:-

2 {m}^{3}  - 5 {m}^{2}  + 3m - 6 - 5 {m}^{3}  + 2 {m}^{2}  - 8x + 2  + 6 +  + 5

Solution:-

2 {m}^{3}  - 5 {m}^{2}  + 3m - 6 - 5 {m}^{3}  + 2 {m}^{2}  - 8x + 2  + 6 +  + 5

Grouping like terms,

2 {m}^{3}  - 5 {m}^{3}

2 {m}^{3}  - 5 {m}^{3}   -  5 {m}^{2}  + 2 {m}^{2}  - 3m - 8x - 6 + 2 + 6 + 5

 =  - 3 {m}^{3}  + 3{m}^{2}  + 3m - 8x - 6 + 13

 =  - 3 {m}^{3}  + 3{m}^{2}  + 3m - 8x  + 7

Therefore the value is,

- 3 {m}^{3}  + 3{m}^{2}  + 3m - 8x  + 7
