each term in (4m+3) must multiply each term in ( 5 m 3 4 m 2 + m 5 ) so that it becomes
4 m ( 5 m 3 4 m 2 + m 5 ) + 3 ( 5 m 3 4 m 2 + m 5 )
multiplying each term by 4m you get
20 m 4 16 m 3 + 4 m 2 20 m
multiplying each term by 3 you get
15 m 3 12 m 2 + 3 m 15
combining these terms-be sure to line up like terms
20 m 4 16 m 3 + 4 m 2 20 m
15 m 3 12 m 2 + 3 m 15
20 m 4 m 3 8 m 2 17 m 15
