Solution for 2+4x-2x^2+4x^3/x-3 equation:


D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

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

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

2*x^2+4*x-1 = 0

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

DELTA = 24

DELTA > 0

x = (24^(1/2)-4)/(2*2) or x = (-24^(1/2)-4)/(2*2)

x = (2*6^(1/2)-4)/4 or x = (-2*6^(1/2)-4)/4

x in { (-2*6^(1/2)-4)/4, (2*6^(1/2)-4)/4 }
