Solution for 18/X=X/2 equation: 


D( X )

X = 0

X = 0

X = 0

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

18/X = X/2 // - X/2

18/X-(X/2) = 0

18*X^-1-1/2*X^1 = 0

(18*X^0-1/2*X^2)/(X^1) = 0 // * X^2

X^1*(18*X^0-1/2*X^2) = 0

X^1

(-1/2)*X^2+18 = 0

(-1/2)*X^2+18 = 0

DELTA = 0^2-(4*18*(-1/2))

DELTA = 36

DELTA > 0

X = (36^(1/2)+0)/(2*(-1/2)) or X = (0-36^(1/2))/(2*(-1/2))

X = -6 or X = 6

X in { -6, 6} 

X in { -6, 6 }
