D( x )
x = 0
x = 0
x = 0
x in (-oo:0) U (0:+oo)
x+1/x = 17/4 // - 17/4
x+1/x-(17/4) = 0
x+1/x-17/4 = 0
1*x^1+1*x^-1-17/4*x^0 = 0
(1*x^2-17/4*x^1+1*x^0)/(x^1) = 0 // * x^2
x^1*(1*x^2-17/4*x^1+1*x^0) = 0
x^1
x^2+(-17/4)*x+1 = 0
x^2+(-17/4)*x+1 = 0
DELTA = (-17/4)^2-(1*1*4)
DELTA = 225/16
DELTA > 0
x = ((225/16)^(1/2)-(-17/4))/(1*2) or x = (-(-17/4)-(225/16)^(1/2))/(1*2)
x = 4 or x = 1/4
x in { 1/4, 4}
x in { 1/4, 4 }
