Solution for 2/2x+1+3/2x-1=2x+2/4x^-1 equation: 


D( x )

x = 0

x = 0

x = 0

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

(2/2)*x+(3/2)*x-1+1 = 2*x+(2/4)*x^-1 // - 2*x+(2/4)*x^-1

(2/2)*x+(3/2)*x-(2*x)-((2/4)*x^-1)-1+1 = 0

(2/2)*x+(3/2)*x-2*x+(-1/2)*x^-1-1+1 = 0

1/2*x^1-1/2*x^-1 = 0

(1/2*x^2-1/2*x^0)/(x^1) = 0 // * x^2

x^1*(1/2*x^2-1/2*x^0) = 0

x^1

(1/2)*x^2-1/2 = 0

(1/2)*x^2-1/2 = 0

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

DELTA = 1

DELTA > 0

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

x = 1 or x = -1

x in { -1, 1} 

x in { -1, 1 }
