Question

Which expression is equivalent to 2m^2-m^2(7-m)+6m^2

Answer 1

2m^2-m^2(7-m)+6m^2
= 2m^2 - 7m^2 + m^3 + 6m^2
= m^3 + m^2

Answer 2

equivalent expression is m^3 + m^2

Explanation:

`2m^2-m^2(7-m)+6m^2`

WE need to simplify the given expression to get equivalent expression

distribute -m^2 inside the parenthesis

`2m^2-7m^2+m^3+6m^2`

Combine like terms

2m^2 -7m^2+6m^2= m^2

So expression becomes
`m^3+m^2`
