D( x )
x = 0
x = 0
x = 0
x in (-oo:0) U (0:+oo)
x-((3/5)*x)-24 = 1/x-4 // - 1/x-4
x-((3/5)*x)-(1/x)-24+4 = 0
x+(-3/5)*x-x^-1-24+4 = 0
2/5*x^1-1*x^-1-20*x^0 = 0
(2/5*x^2-20*x^1-1*x^0)/(x^1) = 0 // * x^2
x^1*(2/5*x^2-20*x^1-1*x^0) = 0
x^1
(2/5)*x^2-20*x-1 = 0
(2/5)*x^2-20*x-1 = 0
DELTA = (-20)^2-(-1*4*(2/5))
DELTA = 2008/5
DELTA > 0
x = ((2008/5)^(1/2)+20)/(2*(2/5)) or x = (20-(2008/5)^(1/2))/(2*(2/5))
x = 5/4*((2008/5)^(1/2)+20) or x = 5/4*(20-(2008/5)^(1/2))
x in { 5/4*(20-(2008/5)^(1/2)), 5/4*((2008/5)^(1/2)+20)}
x in { 5/4*(20-(2008/5)^(1/2)), 5/4*((2008/5)^(1/2)+20) }
