Question

Find the missing terms and write them in decreasing order of exponents.
21m7 − 7m5 + 49m = 7m(

Answer 1

each one of those contains a common factor of 7 and m
factoring is similar to doing this, 7m/7m = 1, multiplying by 1, nothing changed
\[\large \frac{ 7m }{ 7m }*(21m^7-7m^5+49m)\]

Answer 2

notice each of those terms can be divided by 7m cleanly
\[\large 7m*(\frac{ 21m^7 }{ 7m }-\frac{ 7m^5 }{ 7m }+\frac{ 49m }{ 7m })\]

Answer 3

Yes, I understand thank you so much!

Answer 4

giving
\[\large 7m * (3m^6 - 1m^4+7)\]

Answer 5

k, welcome
