Solution for 7x^2/3-27x1/3-4 equation: 


x in (-oo:+oo)

(7*x^2)/3-((27*x^1)/3)-4 = 0

(7*x^2)/3-9*x-4 = 0

7/3*x^2-9*x-4 = 0

DELTA = (-9)^2-(-4*7/3*4)

DELTA = 355/3

DELTA > 0

x = ((355/3)^(1/2)+9)/(2*7/3) or x = (9-(355/3)^(1/2))/(2*7/3)

x = 3/14*((355/3)^(1/2)+9) or x = 3/14*(9-(355/3)^(1/2))

x in { 3/14*(9-(355/3)^(1/2)), 3/14*((355/3)^(1/2)+9) }
