Question

What is the answer to Factor 3a^2-6a

Answer 1

Hi there!

$3 {a}^{2} - 6a \: = 3a(a - 2)$

We can see this by writing the factors as multipliers. We get the following:
$3a {}^{2} = 3 \times \: a \times a$
$6a = 3 \times 2 \times a$

Now we can see that the terms that are in common are 3 and a, and therefore we can bring those outside the parenthesis.
