It can be done either using Bhaskara to find the roots or just go manipulating your equation, as it lacks the

In other words, let's do as follows to isolate

In order to factor, you need to equal each root to zero.

You have your roots already:

Let's just equal each to zero:

Now, you know that

So,

Now solving

is the same as solving

A product (multiply) of two numbers can be

This tells us that to make

We can make

And we can make

The solutions are:
