23.) 2 m ^{7}+ 3 m ^{6} + 2 m ^{4} + 10 m ^{3} + 15 m^{ 2} + 10

Step-by-step explanation:

17.) Distribute to all of the terms in the parenthesis.

18.) Combine Like Terms (x and ) Multiply all other terms by

19.) Multiply terms within the separate parenthesis together

20.) Use FOIL and expand the polynomial

21.) Use FOIL and expand the polynomial

22.) Combine like terms and multiply the contents of the parenthesis by the exponent

23.) Expand  ( m^{ 4} + 5 ) ( 2 m^{ 3} + 3 m ^{2} + 2 )  by multiplying each term in the first expression by each term in the second expression.
