Therefore, we can make a substitution to simplify the expression.
So, let’s let .
Our expression is the same as:
Substitute:
Now, we can factor like normal. We can use -1 and -4. Therefore:
We can now substitute back u:
Both of these can be factored furthered using the difference of two squares:
Therefore, we will have:
And we are done!
