Solution for 3x-2/2x-3=x+12/x+4 equation: 


D( x )

x = 0

x = 0

x = 0

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

3*x-((2/2)*x)-3 = x+12/x+4 // - x+12/x+4

3*x-((2/2)*x)-x-(12/x)-4-3 = 0

3*x-x-x-12*x^-1-4-3 = 0

1*x^1-12*x^-1-7*x^0 = 0

(1*x^2-7*x^1-12*x^0)/(x^1) = 0 // * x^2

x^1*(1*x^2-7*x^1-12*x^0) = 0

x^1

x^2-7*x-12 = 0

x^2-7*x-12 = 0

DELTA = (-7)^2-(-12*1*4)

DELTA = 97

DELTA > 0

x = (97^(1/2)+7)/(1*2) or x = (7-97^(1/2))/(1*2)

x = (97^(1/2)+7)/2 or x = (7-97^(1/2))/2

x in { (7-97^(1/2))/2, (97^(1/2)+7)/2} 

x in { (7-97^(1/2))/2, (97^(1/2)+7)/2 }
