x-x^2=2/3
We move all terms to the left:
x-x^2-(2/3)=0
We add all the numbers together, and all the variables
-x^2+x-(+2/3)=0
We add all the numbers together, and all the variables
-1x^2+x-(+2/3)=0
We get rid of parentheses
-1x^2+x-2/3=0
We multiply all the terms by the denominator
-1x^2*3+x*3-2=0
Wy multiply elements
-3x^2+3x-2=0
a = -3; b = 3; c = -2;
Δ = b2-4ac
Δ = 32-4·(-3)·(-2)
Δ = -15
Delta is less than zero, so there is no solution for the equation
