#=(x-d)(1+x-d)#

#x-d+(x-d)^2#
#=(x-d)(1+x-d)#

#(x-d)(1+x-d)#

Before we try to factorise, let's make 2 small changes:
There are 3 terms, but group the first two so that we have 2 terms.

#color(red)((x-d)) + color(red)((x-d))(x-d) " there is a common bracket"#

#color(red)((x-d))(1+x-d)#

There are two factors.
