Solution for 3x^2-3x/9x^2+15x equation: 


x in (-oo:+oo)

3*x^2-(((3*x)/9)*x^2)+15*x = 0

(-1/3)*x^3+3*x^2+15*x = 0

3*x^2-1/3*x^3+15*x = 0

x*(3*x-1/3*x^2+15) = 0

3*x-1/3*x^2+15 = 0

DELTA = 3^2-(-1/3*4*15)

DELTA = 29

DELTA > 0

x = (29^(1/2)-3)/(-1/3*2) or x = (-29^(1/2)-3)/(-1/3*2)

x = -3/2*(29^(1/2)-3) or x = 3/2*(29^(1/2)+3)

x = 0

x = 0

x in { -3/2*(29^(1/2)-3), 3/2*(29^(1/2)+3), 0 }
