Question

15c² - 5c. Factorise completely ​

Answer 1

5c(3c - 1)

Explanation:

Take out the 5c to factor out completely

Answer 2

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)`.
