Note: I assume there is a typo. The expression could be

$x^2+3xa+6x + 18a$

We can factor this expression using Grouping. Making groups of 2 terms each, we get:

$= (x^2+3xa)+(6x + 18a)$

$x$ is common to both the terms in the first group, and $6$ is common to both the terms in the second group.

$= x(x+3a)+6(x + 3a)$

$x+3a$ is common to both the terms

$=color(green)((x+3a)(x+6)$
