Solution for 2=-32/x3 equation: 


D( x )

x^3 = 0

x^3 = 0

x^3 = 0

1*x^3 = 0 // : 1

x^3 = 0

x = 0

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

2 = -32/(x^3) // + -32/(x^3)

2-(-32/(x^3)) = 0

32*x^-3+2 = 0

32*x^-3 = -2 // : 32

x^-3 = -1/16

-3 < 0

1/(x^3) = -1/16 // * x^3

1 = -1/16*x^3 // : -1/16

-16 = x^3

x^3 = -16 // ^ 1/3

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

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