Solution for 10/5x^2-20x-60=0 equation: 


x in (-oo:+oo)

(10/5)*x^2-(20*x)-60 = 0

(10/5)*x^2-20*x-60 = 0

2*x^2-20*x-60 = 0

DELTA = (-20)^2-(-60*2*4)

DELTA = 880

DELTA > 0

x = (880^(1/2)+20)/(2*2) or x = (20-880^(1/2))/(2*2)

x = (4*55^(1/2)+20)/4 or x = (20-4*55^(1/2))/4

x in { (20-4*55^(1/2))/4, (4*55^(1/2)+20)/4 }
