Hi, berserk! The easiest way to solve this problem is probably trial and error, but if you want the general solution with a more systematic approach:

Let the roots of our quadratic be . We have and . This gives us the system of linear equations:

Now, let be some arbitrary value . Then we have as our solution:

Now just pick a (nonzero) value for ! For example, with we have
