Answer:

#2(7x +2)#

Explanation:

Here,

Since 5 and 9 have same variable #x#, you can add these two. But since 4 has no variable and is different from a term containing x, you cannot add it with other terms.

SO,

=#5x +4 +9x#
= # 14x +4 #

You can even take a digit common. In this case 2 goes common for both terms so

= #2(7x +2)#
