See a solution process below:

Explanation:

We can rewrite the expression as:

#(5 * 2x) - (5 * 3)#

We can then factor out the common term:

#5(2x - 3)#

factor out the common factor of 5

Explanation:

# 10 x = 2 xx 5 xx x #
# -15 = -1 xx 3 xx 5#

There is a common factor of 5 so
# (10x - 15 ) = {( 10x - 15) xx 5}/5#

# {(10x -15) xx 5}/5 = ( 2x -3) xx 5# or

# 5 ( 2x -3)#
