First, rewrite this expression as:

Answer:

#=9(3+4x)#

Explanation:

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#
