A quadratic function has roots at x = 2 and x = -3. Write the quadratic equation in standard form and find the vertex of the parabola.

• The quadratic equation is f(x) = x^2 + x - 6 and the vertex is (-1/2, -25/4).

• f(x) = x^2 - x + 6 and the vertex is (1/2, 25/4)

• f(x) = x^2 + 5x + 6 and the vertex is (-5/2, -25/4)

• f(x) = x^2 - 5x - 6 and the vertex is (5/2, -25/4)
