3x^2 - 5x - 1 = 0 is a quadratic with coefficients {3, -5, -1}. Find the discriminant b^2 - 4ac: 25 - 4(3)(-1) = 13.
Because the discriminant is positive, we know we have two unequal real roots here. Continuing with the quadratic formula, we obtain:
-(-5) ±√13 5 ± √13
x = ----------------- = ----------------
2(3) 6
