12) 
Square both sides. Put all numbers on one side of the equation so that you can be equal to zero. Factor out and solve for x.
k = 0 means the parabola has one zero, because the vertex is just on the x-axis. k > 0 means the parabola has none zeros, because the vertex will be above the x-axis and it will not intersect the x - axis.
