Solution for 2/3x=1/3x^2 equation:


x in (-oo:+oo)

(2/3)*x = (1/3)*x^2 // - (1/3)*x^2

(2/3)*x-((1/3)*x^2) = 0

(-1/3)*x^2+(2/3)*x = 0

2/3*x-1/3*x^2 = 0

DELTA = (2/3)^2-(-1/3*0*4)

DELTA = 4/9

DELTA > 0

x = ((4/9)^(1/2)-2/3)/(-1/3*2) or x = (-(4/9)^(1/2)-2/3)/(-1/3*2)

x = 0 or x = 2

x in { 0, 2 }
