=color(blue)(4a +2b

#### Explanation:

$\textcolor{b l u e}{2} \left(2 a + b\right)$

Here $\textcolor{b l u e}{2}$ needs to be multiplied with both the terms within the bracket.

$= \textcolor{b l u e}{2} \times \left(2 a\right) + \textcolor{b l u e}{2} \times \left(b\right)$

=color(blue)(4a +2b
