Question 1145783
A model rocket is launched with an initial an initial upward velocity of 50 m/s. The rockets height “h” (in meters) after “t” seconds is given by the following. 
H=50t-5t squared 
Find all values of “t” for which the rockets height is 20 meters
-------
H=50t-5t^2 = 20
t^2 - 10t + 4 = 0
*[invoke solve_quadratic_equation 1,-10,4]
==================
This is more descriptive:
-5t^2 + 50t - 20 = 0
*[invoke solve_quadratic_equation -5,50,-20]
