Solution for 5x^2-5x-30/10x-30 equation: 


x in (-oo:+oo)

5*x^2-(5*x)-((30/10)*x)-30 = 0

5*x^2-5*x-3*x-30 = 0

5*x^2-8*x-30 = 0

DELTA = (-8)^2-(-30*4*5)

DELTA = 664

DELTA > 0

x = (664^(1/2)+8)/(2*5) or x = (8-664^(1/2))/(2*5)

x = (2*166^(1/2)+8)/10 or x = (8-2*166^(1/2))/10

x in { (8-2*166^(1/2))/10, (2*166^(1/2)+8)/10 }
