Respuesta :

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

Answer:

equivalent expression is m^3 + m^2

Step-by-step explanation:

[tex]2m^2-m^2(7-m)+6m^2[/tex]

WE need to simplify the given expression to get equivalent expression

distribute -m^2 inside the parenthesis

[tex]2m^2-7m^2+m^3+6m^2[/tex]

Combine like terms

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

So expression becomes [tex]m^3+m^2[/tex]
