39.73=x(1-x)
We move all terms to the left:
39.73-(x(1-x))=0
We add all the numbers together, and all the variables
-(x(-1x+1))+39.73=0
We calculate terms in parentheses: -(x(-1x+1)), so:We get rid of parentheses
x(-1x+1)
We multiply parentheses
-1x^2+x
Back to the equation:
-(-1x^2+x)
1x^2-x+39.73=0
We add all the numbers together, and all the variables
x^2-1x+39.73=0
a = 1; b = -1; c = +39.73;
Δ = b2-4ac
Δ = -12-4·1·39.73
Δ = -157.92
Delta is less than zero, so there is no solution for the equation
