Solution for 7h^2-12/h equation: 


D( h )

h = 0

h = 0

h = 0

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

7*h^2-(12/h) = 0

7*h^2-12*h^-1 = 0

7*h^2-12*h^-1 = 0

h^-1*(7*h^3-12) = 0

7*h^3 = 12 // : 7

h^3 = 12/7

h^3 = 12/7 // ^ 1/3

h = (12/7)^(1/3)

1/h = 0

1*h^-1 = 0 // : 1

h^-1 = 0

h należy do O

h = (12/7)^(1/3)
