#=color(blue)((7x-3) (2y-1) #

Explanation:

#14xy-7x-6y+3#

We can factor this expression by making groups of two terms:
#color(blue)((14xy-7x)) + color(green)((-6y+3)#

#7x# is common to both the terms in the first group, and #-3# is common to both the terms in the second group:

#=7x(2y-1) -3 (2y-1)#

#(2y-1)# is common to both the terms now
#=color(blue)((7x-3) (2y-1) #
