Solution for 6-622/u^2+5u-6 equation: 


D( u )

u^2 = 0

u^2 = 0

u^2 = 0

1*u^2 = 0 // : 1

u^2 = 0

u = 0

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

5*u-(622/(u^2))-6+6 = 0

5*u-622*u^-2-6+6 = 0

5*u-622*u^-2 = 0

u*(5-622*u^-3) = 0

-622*u^-3 = -5 // : -622

u^-3 = 5/622

-3 < 0

1/(u^3) = 5/622 // * u^3

1 = 5/622*u^3 // : 5/622

622/5 = u^3

u^3 = 622/5 // ^ 1/3

u = (622/5)^(1/3)

u = 0

u = 0

u in { 0} 

u = (622/5)^(1/3)
