21m7 − 7m5 + 49m = 7m(____+____+_____ )

Answer 1

21m^7 - 7m^5 + 49m = 

7m(3m^6 + (- m^4) + 7) <==

Answer 2

Answer: $21m^7-7m^5+49=7m(3m^6-m^4+7)$

Explanation: Given expression $21m^7-7m^5+49m$

We can write , $21m^7-7m^5+49= 7m\times3m^6- 7m\times m^4+7m\times7$

Since, in the right side of the above expression 7m is common in every term. so, we can take it common with help of bracket.

Therefore, $21m^7-7m^5+49= 7m(3m^6-m^4+7)$
