Answer:

Step-by-step explanation:

I can guess what the instructions are, but it'd be helpful if you were to share them.

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
