Solution for 2x^2-20x+50/10x^2-30x-100 equation: 


x in (-oo:+oo)

2*x^2+(50/10)*x^2-(20*x)-(30*x)-100 = 0

2*x^2+(50/10)*x^2-20*x-30*x-100 = 0

7*x^2-50*x-100 = 0

DELTA = (-50)^2-(-100*4*7)

DELTA = 5300

DELTA > 0

x = (5300^(1/2)+50)/(2*7) or x = (50-5300^(1/2))/(2*7)

x = (10*53^(1/2)+50)/14 or x = (50-10*53^(1/2))/14

x in { (50-10*53^(1/2))/14, (10*53^(1/2)+50)/14 }
