Question

Instructions:Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar and ^ to indicate an exponent.

Find the missing terms and write them in decreasing order of exponents.
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)`

Step-by-step explanation: Given expression
`21m^7-7m^5+49m`

We can write ,
`21m^7-7m^5+49= 7m*3m^6- 7m* m^4+7m*7`

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)`
