Solution for 45x^2-x^3/45-x equation: 


x in (-oo:+oo)

45*x^2-((x^3)/45)-x = 0

45*x^2-1/45*x^3-x = 0

x*(45*x-1/45*x^2-1) = 0

45*x-1/45*x^2-1 = 0

DELTA = 45^2-(-1*(-1/45)*4)

DELTA = 91121/45

DELTA > 0

x = ((91121/45)^(1/2)-45)/(-1/45*2) or x = (-(91121/45)^(1/2)-45)/(-1/45*2)

x = -45/2*((91121/45)^(1/2)-45) or x = 45/2*((91121/45)^(1/2)+45)

x = 0

x = 0

x in { -45/2*((91121/45)^(1/2)-45), 45/2*((91121/45)^(1/2)+45), 0 }
