See a solution process below:

First, rewrite this expression as:

$(9 xx 3) + (9 xx 4x)$

Now, factor a $9$ out of each term:

$9(3 + 4x)$

$=9(3+4x)$

the first step in factorising is to look for any common factors.

$27 and 36$ are both multiples of $3 and 9$ .

We use $9$ because it is the highest common factor:
Divide $9$ out of each term:

$27 +36x$

$=9(3+4x)$

The reverse process would be to use the distributive law to multiply each term in the bracket by $9$ .
This will give us the original expression:

$9(3+4x) = 27+36x$
