Since they aren't like terms the outcome is 3ab-7bc.
Basically the answer was already there.

Answer:

[tex]b(3a-7c)[/tex]

Step-by-step explanation:

the difference of 3ab and 7bc

To find the difference we subtract the terms

the difference of 3ab and 7bc is 3ab - 7bc

3ab can be written as 3*a*b

7bc can be written as 8*b*c

Common factor is 'b'

GCF is 'b'

WE put GCF outside and write the remaining terms inside the parenthesis

[tex]b(3a-7c)[/tex]
