Answer 1

Answer:

${m}^{3} ( {m}^{4} - 2 {m }^{2} + 3m + 2) - 2m( {m}^{4} - 2 {m }^{2} + 3m + 2) + 3( {m}^{4} - 2 {m }^{2} + 3m + 2) \\ = {m}^{7} - 2 {m}^{5} + 3 {m}^{4} + 2 {m}^{3} - 2 {m}^{5} + 4 {m}^{3} - 6 {m}^{2} - 4m + 3 {m}^{4} - 6 {m}^{2} + 9m + 6 \\ = {m}^{7} - 2 {m}^{5 } - 2 {m}^{5} + 3 {m}^{4} + 3 {m}^{4} + 4 {m}^{3} + 3 {m}^{3} - 6 {m}^{2} - 6 {m}^{2} - 4m + 9m + 6 \\ = {m}^{7} - 4 {m}^{5} + 6 {m}^{4} + 7 {m}^{3} - 12 {m}^{2} + 5m + 6$
