Solution for 3/X-2X=1 equation: 


D( X )

X = 0

X = 0

X = 0

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

3/X-(2*X) = 1 // - 1

3/X-(2*X)-1 = 0

3/X-2*X-1 = 0

3*X^-1-2*X^1-1*X^0 = 0

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

X^1*(3*X^0-2*X^2-1*X^1) = 0

X^1

3-2*X^2-X = 0

3-2*X^2-X = 0

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

DELTA = 25

DELTA > 0

X = (25^(1/2)+1)/(-2*2) or X = (1-25^(1/2))/(-2*2)

X = -3/2 or X = 1

X in { -3/2, 1} 

X in { -3/2, 1 }
