Solution for 12*x^3-11/2*x^2-15/4*x equation: 


x in (-oo:+oo)

12*x^3-((11/2)*x^2)-((15/4)*x) = 0

12*x^3+(-11/2)*x^2+(-15/4)*x = 0

12*x^3-11/2*x^2-15/4*x = 0

x*(12*x^2-11/2*x-15/4) = 0

12*x^2-11/2*x-15/4 = 0

DELTA = (-11/2)^2-(-15/4*4*12)

DELTA = 841/4

DELTA > 0

x = ((841/4)^(1/2)+11/2)/(2*12) or x = (11/2-(841/4)^(1/2))/(2*12)

x = 5/6 or x = -3/8

x = 0

x = 0

x in { -3/8, 5/6, 0 }
