If the equation is in vertex form:

 

1)  If the vertex is on the x-axis, there is one root (a double root)

2)  If the vertex is above the x-axis and the parabola rises, there are no real roots.

3)  If the vertex is above the x-axis and the parabola falls, there are two real roots.

4)  If the vertex is below the x-axis and the parabola rises, there are two real roots.

5)  If the vertex is below the x-axis and the parabola falls, there are no real roots.
