Solution for (8h^2)/(3h+h^2) equation: 


D( h )

h^2+3*h = 0

h^2+3*h = 0

h^2+3*h = 0

h^2+3*h = 0

DELTA = 3^2-(0*1*4)

DELTA = 9

DELTA > 0

h = (9^(1/2)-3)/(1*2) or h = (-9^(1/2)-3)/(1*2)

h = 0 or h = -3

h in (-oo:-3) U (-3:0) U (0:+oo)

(8*h^2)/(h^2+3*h) = 0

h^2+3*h = 0

h*(h+3) = 0

h+3 = 0 // - 3

h = -3

h*(h+3) = 0

(8*h^2)/(h*(h+3)) = 0

8*h^2 = 0 // : 8

h^2 = 0

h = 0

h in { 0} 

h belongs to the empty set
