Solution for 2x^2/3-x^1/3=28 equation: 


x in (-oo:+oo)

(2*x^2)/3-((x^1)/3) = 28 // - 28

(2*x^2)/3-((x^1)/3)-28 = 0

(2*x^2)/3-(x/3)-28 = 0

2/3*x^2-1/3*x-28 = 0

DELTA = (-1/3)^2-(-28*2/3*4)

DELTA = 673/9

DELTA > 0

x = ((673/9)^(1/2)+1/3)/(2/3*2) or x = (1/3-(673/9)^(1/2))/(2/3*2)

x = 3/4*((673/9)^(1/2)+1/3) or x = 3/4*(1/3-(673/9)^(1/2))

x in { 3/4*(1/3-(673/9)^(1/2)), 3/4*((673/9)^(1/2)+1/3) }
