Solution for x-3/x+2=4/5 equation: 


D( x )

x = 0

x = 0

x = 0

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

x-(3/x)+2 = 4/5 // - 4/5

x-(3/x)-(4/5)+2 = 0

x-3*x^-1-4/5+2 = 0

1*x^1-3*x^-1+6/5*x^0 = 0

(1*x^2+6/5*x^1-3*x^0)/(x^1) = 0 // * x^2

x^1*(1*x^2+6/5*x^1-3*x^0) = 0

x^1

x^2+(6/5)*x-3 = 0

x^2+(6/5)*x-3 = 0

DELTA = (6/5)^2-(-3*1*4)

DELTA = 336/25

DELTA > 0

x = ((336/25)^(1/2)-(6/5))/(1*2) or x = (-(6/5)-(336/25)^(1/2))/(1*2)

x = ((336/25)^(1/2)-6/5)/2 or x = (-((336/25)^(1/2)+6/5))/2

x in { (-((336/25)^(1/2)+6/5))/2, ((336/25)^(1/2)-6/5)/2} 

x in { (-((336/25)^(1/2)+6/5))/2, ((336/25)^(1/2)-6/5)/2 }
