Solution for 2x^2-18/6x-18 equation: 


x in (-oo:+oo)

2*x^2-((18/6)*x)-18 = 0

2*x^2-3*x-18 = 0

2*x^2-3*x-18 = 0

DELTA = (-3)^2-(-18*2*4)

DELTA = 153

DELTA > 0

x = (153^(1/2)+3)/(2*2) or x = (3-153^(1/2))/(2*2)

x = (3*17^(1/2)+3)/4 or x = (3-3*17^(1/2))/4

x in { (3-3*17^(1/2))/4, (3*17^(1/2)+3)/4 }
