0=6t+4.9t^2+20
We move all terms to the left:
0-(6t+4.9t^2+20)=0
We add all the numbers together, and all the variables
-(6t+4.9t^2+20)=0
We get rid of parentheses
-4.9t^2-6t-20=0
a = -4.9; b = -6; c = -20;
Δ = b2-4ac
Δ = -62-4·(-4.9)·(-20)
Δ = -356
Delta is less than zero, so there is no solution for the equation
