Question

UpStudy AI · Accepted Answer

To simplify the expression $$ 5 m^{2} + 2.3 + 4 m - 0.8 - 2 m + m^{2} $$, follow these steps to combine like terms:

1. **Combine the $$ m^{2} $$ terms:**
   $$
   5m^{2} + m^{2} = 6m^{2}
   $$

2. **Combine the $$ m $$ terms:**
   $$
   4m - 2m = 2m
   $$

3. **Combine the constant terms:**
   $$
   2.3 - 0.8 = 1.5
   $$

Putting it all together, the simplified expression is:
$$
6m^{2} + 2m + 1.5
$$

**Final Answer:**
$$
6m^{2} + 2m + 1.5
$$
The simplified expression is $$ 6m^{2} + 2m + 1.5 $$.
