Solution for (39x^2-460x-2380)/76000=0 equation: 


x in (-oo:+oo)

(39*x^2-(460*x)-2380)/76000 = 0

(39*x^2-460*x-2380)/76000 = 0

39*x^2-460*x-2380 = 0

39*x^2-460*x-2380 = 0

DELTA = (-460)^2-(-2380*4*39)

DELTA = 582880

DELTA > 0

x = (582880^(1/2)+460)/(2*39) or x = (460-582880^(1/2))/(2*39)

x = (4*36430^(1/2)+460)/78 or x = (460-4*36430^(1/2))/78

(x-((460-4*36430^(1/2))/78))*(x-((4*36430^(1/2)+460)/78)) = 0

((x-((460-4*36430^(1/2))/78))*(x-((4*36430^(1/2)+460)/78)))/76000 = 0

( x-((4*36430^(1/2)+460)/78) )

x-((4*36430^(1/2)+460)/78) = 0 // + (4*36430^(1/2)+460)/78

x = (4*36430^(1/2)+460)/78

( x-((460-4*36430^(1/2))/78) )

x-((460-4*36430^(1/2))/78) = 0 // + (460-4*36430^(1/2))/78

x = (460-4*36430^(1/2))/78

x in { (4*36430^(1/2)+460)/78, (460-4*36430^(1/2))/78 }
