(T)=0.1T^2+2.155T+19.985
We move all terms to the left:
(T)-(0.1T^2+2.155T+19.985)=0
We get rid of parentheses
-0.1T^2+T-2.155T-19.985=0
We add all the numbers together, and all the variables
-0.1T^2-1.155T-19.985=0
a = -0.1; b = -1.155; c = -19.985;
Δ = b2-4ac
Δ = -1.1552-4·(-0.1)·(-19.985)
Δ = -6.659975
Delta is less than zero, so there is no solution for the equation
