Solution for x^2/5-x^1/5-2=0 equation: 


x in (-oo:+oo)

(x^2)/5-((x^1)/5)-2 = 0

(x^2)/5-(x/5)-2 = 0

1/5*x^2-1/5*x-2 = 0

DELTA = (-1/5)^2-(-2*1/5*4)

DELTA = 41/25

DELTA > 0

x = ((41/25)^(1/2)+1/5)/(1/5*2) or x = (1/5-(41/25)^(1/2))/(1/5*2)

x = 5/2*((41/25)^(1/2)+1/5) or x = 5/2*(1/5-(41/25)^(1/2))

x in { 5/2*(1/5-(41/25)^(1/2)), 5/2*((41/25)^(1/2)+1/5) }
