0=-4.9t^2+t-2.201
We move all terms to the left:
0-(-4.9t^2+t-2.201)=0
We add all the numbers together, and all the variables
-(-4.9t^2+t-2.201)=0
We get rid of parentheses
4.9t^2-t+2.201=0
We add all the numbers together, and all the variables
4.9t^2-1t+2.201=0
a = 4.9; b = -1; c = +2.201;
Δ = b2-4ac
Δ = -12-4·4.9·2.201
Δ = -42.1396
Delta is less than zero, so there is no solution for the equation
