Solution for (5/3x)^2-(13/3x)-2=0 equation: 


x in (-oo:+oo)

((5/3)*x)^2-((13/3)*x)-2 = 0

((5/3)*x)^2+(-13/3)*x-2 = 0

25/9*x^2-13/3*x-2 = 0

DELTA = (-13/3)^2-(-2*25/9*4)

DELTA = 41

DELTA > 0

x = (41^(1/2)+13/3)/(2*25/9) or x = (13/3-41^(1/2))/(2*25/9)

x = 9/50*(41^(1/2)+13/3) or x = 9/50*(13/3-41^(1/2))

x in { 9/50*(13/3-41^(1/2)), 9/50*(41^(1/2)+13/3) }
