# How do you factor 2x(x+3)+4(x+3)?

$\left(2 x + 4\right) \left(x + 3\right)$
Looking at the expression, you can see that the expression $\left(x + 3\right)$ is common to both $2 x \left(x + 3\right)$ and $4 \left(x + 3\right)$ . The equation can therefore be written as
$\left(2 x + 4\right) \left(x + 3\right)$
