263.158=x-x^2
We move all terms to the left:
263.158-(x-x^2)=0
We get rid of parentheses
x^2-x+263.158=0
We add all the numbers together, and all the variables
x^2-1x+263.158=0
a = 1; b = -1; c = +263.158;
Δ = b2-4ac
Δ = -12-4·1·263.158
Δ = -1051.632
Delta is less than zero, so there is no solution for the equation
