math question

A small toy rocket is launched from a 30-foot pad. The height (h, in feet) of the rocket t seconds after taking off is given by the formula
h= -2x2 -4x + 30 
How long will it take the rocket to hit the ground?

The equation in the problem statement cannot be right unless the rocket is fired straight down.  Please double check the sign of the second term.
