Question

15c² - 5c. Factorise completely ​

Answer 1

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

• $15c^2 - 5c$

• $5c(\frac{15c^2}{5c}) - 5c(\frac{5c}{5c})$

• $5c(3c) - 5c(1)$

• $5c(3c - 1)$

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