Step-by-step explanation:
Hope this helps.
Set the quadratic = to 0 and solve for time, t:
-16t^2 - 8t + 20 = 0
Reduce this to:
-4t^2 - 2t + 5 = 0
Here a= -4, b= -2 and c =5. Then,
2 plus or minus sqrt( 4-4(-4)(5) )
t = ---------------------------------------------
-8
2 plus or minus sqrt(84)
= ------------------------------------
-8
Finish evaluating this. If either outcome is negative, discard it.
