Looking at the problem, what we must do to complete this question is to completely factor the expression that was provided. The expression that was provided is
15c^2 - 5c.

The first step that we must do is to take a look at the expression and see what the two pieces of the expression have in common. We can see that both
15c^2 and
-5c have the number 5 and the variable c associated with them so we can factor out those two.

Factor out 5c


  • 15c^2 - 5c

  • 5c((15c^2)/(5c)) - 5c((5c)/(5c))

  • 5c(3c) - 5c(1)

  • 5c(3c - 1)

Now we have completely factored out the expression that was provided in the problem statement and we came to final answer of
5c(3c - 1).
