Solution for 12-17x-5x^2/3-5x equation: 


x in (-oo:+oo)

12-((5*x^2)/3)-(17*x)-(5*x) = 0

(-5/3)*x^2-17*x-5*x+12 = 0

12-5/3*x^2-22*x = 0

DELTA = (-22)^2-(-5/3*4*12)

DELTA = 564

DELTA > 0

x = (564^(1/2)+22)/(-5/3*2) or x = (22-564^(1/2))/(-5/3*2)

x = -3/10*(2*141^(1/2)+22) or x = -3/10*(22-2*141^(1/2))

x in { -3/10*(2*141^(1/2)+22), -3/10*(22-2*141^(1/2)) }
