D( x )

x^2 = 0

x^2 = 0

x^2 = 0

1*x^2 = 0 // : 1

x^2 = 0

x = 0

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

4*x-(3*x)-(7/(x^2))+2/(x^2)-25+25 = 0

4*x-3*x-7*x^-2+2/(x^2)-25+25 = 0

x-5*x^-2 = 0

x*(1-5*x^-3) = 0

-5*x^-3 = -1 // : -5

x^-3 = 1/5

-3 < 0

1/(x^3) = 1/5 // * x^3

1 = 1/5*x^3 // : 1/5

5 = x^3

x^3 = 5 // ^ 1/3

x = 5^(1/3)

x = 0

x = 0

x in { 0} 

x = 5^(1/3)
