Solution for 6x^2-13x-5/9x^3-x equation: 


x in (-oo:+oo)

6*x^2-((5/9)*x^3)-(13*x)-x = 0

(-5/9)*x^3+6*x^2-13*x-x = 0

6*x^2-5/9*x^3-14*x = 0

x*(6*x-5/9*x^2-14) = 0

6*x-5/9*x^2-14 = 0

DELTA = 6^2-(-14*(-5/9)*4)

DELTA = 44/9

DELTA > 0

x = ((44/9)^(1/2)-6)/(-5/9*2) or x = (-(44/9)^(1/2)-6)/(-5/9*2)

x = -9/10*((44/9)^(1/2)-6) or x = 9/10*((44/9)^(1/2)+6)

x = 0

x = 0

x in { -9/10*((44/9)^(1/2)-6), 9/10*((44/9)^(1/2)+6), 0 }
