Question
Collect like terms and simplify the expression: $12 m^2-9 m+5 m-4 m^2-7 m+10$
✓
Answer
By rearranging the terms in the given expression, we get
$12 m^2-4 m^2+5 m-9 m-7 m+10$
$=(12-4) m^2+(5-9-7) m+10$
$=8 m^2+(-4-7) m+10$
$=8 m^2+(-11) m+10$
$=8 m^2-11 m+10$
$12 m^2-4 m^2+5 m-9 m-7 m+10$
$=(12-4) m^2+(5-9-7) m+10$
$=8 m^2+(-4-7) m+10$
$=8 m^2+(-11) m+10$
$=8 m^2-11 m+10$
