Vertex of Quadratic Equation

Consider the quadratic equation given by:

$$2x^2 - 4x - 6 = 0$$

Determine the x-coordinate of the vertex of the parabola represented by this equation. Remember that the x-coordinate of the vertex for a quadratic equation in the form $$ax^2 + bx + c$$ is calculated using the formula:

$$x = -\frac{b}{2a}$$
