Answer 5

great, lets pull that out first

Answer 6

\(4m^2n^3-20mn^4 \)

\(4 ( ? ) \)

5

Answer 8

\(4m^2n^3-20mn^4 \)

\(4(m^2n^3-5mn^4) \)

Answer 9

right ?

Answer 10

also, m is there in both terms, so we can pull that out as common as well

Answer 11

\(4(m^2n^3-5mn^4) \)

\(4m(mn^3-5n^4) \)

Answer 12

\(n^3 \) is also common in both the terms, right ? pull that also out and see what u get

Answer 13

4m^2-5m
4m(m-5)

il show u

Answer 16

ok

Answer 17

\(4m(mn^3-5n^4) \)

take \(n^3\) common,

\(4mn^3(m-5n ) \)

Answer 18

ok, thank u
