<h3>
<u>Explanation</u></h3>

- Factor the expression by using common factor.
We csn pull out 3x² out of the expression.

We simply pull out the x-term with lowest degree and 3 out of the expression. If another expression cannot be factored after first factoring then that's the final answer.
- The expression can still be factored. Factor the expression by using two brackets.
