$\left(w + 3\right) \left(w + 1\right)$

#### Explanation:

In this case, since $a = 1$ (in $a {x}^{2} + b x + c$), simply look for two numbers whose sum is $4$ and whose product is $3$. You can easily see that the two numbers are $1$ and $3$.

Then, just write it down: $\left(w + 3\right) \left(w + 1\right)$

Check: try expanding the brackets using FOIL.
