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

Answer:

equivalent expression is m^3 + m^2

Step-by-step 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 $m^3+m^2$
