This question is about equations reducible to quadratics:
Gerald hits his golf ball down the fairway. The path the ball followed was parabolic in shape with the relationship:
h=2d1/30d^2
where h is the height above the ground of the golf ball when it is a horizontal distance d from him. Both h and d are in metres. How far from Gerald did the golf ball land?

0 = 2d (1/30) d^2 = d [2  (1/30)d ]
it is at ground level when d = 0 and when
2  d/30 = 0
or when d = 60
