Solution for 2x^3-15/3x^2-3x=0 equation: 


x in (-oo:+oo)

2*x^3-((15/3)*x^2)-(3*x) = 0

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

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

x*(2*x^2-5*x-3) = 0

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

DELTA = (-5)^2-(-3*2*4)

DELTA = 49

DELTA > 0

x = (49^(1/2)+5)/(2*2) or x = (5-49^(1/2))/(2*2)

x = 3 or x = -1/2

x = 0

x = 0

x in { -1/2, 3, 0 }
