Question

Just two Algebra questions. Thank you :)

Answer 1

`4m^6 - 16m^(10)`


`= (2m^3)^2 - (4p^5)^2`


`= (2m^3 -4p^5)(2m^3 + 4p^5)`

================================
This expression is the difference of 2 squares :


`\bf 9n^4 - 49n^6`


`= (3n^2)^2 - (7n^4)^2`


`= (3n^2 + 7n^4) (3n^2 - 7n^4)`
