Solution for x^2-(4/3)x=2/3 equation: 


x in (-oo:+oo)

x^2-((4/3)*x) = 2/3 // - 2/3

x^2-((4/3)*x)-(2/3) = 0

x^2+(-4/3)*x-2/3 = 0

x^2-4/3*x-2/3 = 0

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

DELTA = 40/9

DELTA > 0

x = ((40/9)^(1/2)+4/3)/(1*2) or x = (4/3-(40/9)^(1/2))/(1*2)

x = ((40/9)^(1/2)+4/3)/2 or x = (4/3-(40/9)^(1/2))/2

x in { (4/3-(40/9)^(1/2))/2, ((40/9)^(1/2)+4/3)/2 }
