Solution for 2x^2-72/4x-24 equation: 


x in (-oo:+oo)

2*x^2-((72/4)*x)-24 = 0

2*x^2-18*x-24 = 0

2*x^2-18*x-24 = 0

DELTA = (-18)^2-(-24*2*4)

DELTA = 516

DELTA > 0

x = (516^(1/2)+18)/(2*2) or x = (18-516^(1/2))/(2*2)

x = (2*129^(1/2)+18)/4 or x = (18-2*129^(1/2))/4

x in { (18-2*129^(1/2))/4, (2*129^(1/2)+18)/4 }
