Solve for t when the object hits the ground. Fill in the blanks of the quadratic formula.

If an object is thrown vertically upward with an initial velocity of v, from an originial position of s, the height h at any time t is given by 
h = -16t^2 +vt + s (where h and s are in ft, t is in seconds and v is in ft/sec.) (when h = 0) 
t=blank1+-sqrt(blank2-4(blank3))
   __________________________
                   2(-16)
Fill in the blanks of the quadratic formula. Blank 1, Blank 2, and Blank 3

I'm a little confused on which things exactly are Blank 1, Blank 2, and Blank 3?

Blank 1 = -v
Blank 2 = v2
Blank 3 = -16s
 
Does this help?
