To write the vertex form equation of the parabola (y = -x^2 + 4x + 12), complete the square on the quadratic expression. This involves rearranging the equation to isolate the squared term and then adding or subtracting a constant term to complete the square. The vertex form equation is (y = a(x - h)^2 + k), where ((h, k)) represents the vertex of the parabola.
