Assuming you know the quadratic formula:
You can fill in a, b and c in this and get:
Now, let's create a shorthand 
to make the writing easier:
But since one root is three times the other root (but we don't know which one), we also know that:
or 
If you solve this, you get:
or 
However, since q is a square root, it must be postive.
So we know that:
From this you find that
So p = 3/2
The roots are x=1/2 and x=3/2.
