Solution for 4/6x2-26x-12 equation: 


x in (-oo:+oo)

(4/6)*x^2-(26*x)-12 = 0

(4/6)*x^2-26*x-12 = 0

2/3*x^2-26*x-12 = 0

DELTA = (-26)^2-(-12*2/3*4)

DELTA = 708

DELTA > 0

x = (708^(1/2)+26)/(2/3*2) or x = (26-708^(1/2))/(2/3*2)

x = 3/4*(2*177^(1/2)+26) or x = 3/4*(26-2*177^(1/2))

x in { 3/4*(26-2*177^(1/2)), 3/4*(2*177^(1/2)+26) }
