11.5175386+3.15976x+x2=3.94
We move all terms to the left:
11.5175386+3.15976x+x2-(3.94)=0
We add all the numbers together, and all the variables
x^2+3.15976x+7.5775386=0
a = 1; b = 3.15976; c = +7.5775386;
Δ = b2-4ac
Δ = 3.159762-4·1·7.5775386
Δ = -20.3260711424
Delta is less than zero, so there is no solution for the equation
