20=16t^2+1444
We move all terms to the left:
20-(16t^2+1444)=0
We get rid of parentheses
-16t^2-1444+20=0
We add all the numbers together, and all the variables
-16t^2-1424=0
a = -16; b = 0; c = -1424;
Δ = b2-4ac
Δ = 02-4·(-16)·(-1424)
Δ = -91136
Delta is less than zero, so there is no solution for the equation
