0=9.8t^2
We move all terms to the left:
0-(9.8t^2)=0
We add all the numbers together, and all the variables
-(9.8t^2)=0
We get rid of parentheses
-9.8t^2=0
a = -9.8; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·(-9.8)·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
Stosujemy wzór:$t=\frac{-b}{2a}=\frac{0}{-19.6}=0$
