D( X )
X = 0
X = 0
X = 0
X in (-oo:0) U (0:+oo)
X+3/X+97 = 0
1*X^1+3*X^-1+97*X^0 = 0
(1*X^2+97*X^1+3*X^0)/(X^1) = 0 // * X^2
X^1*(1*X^2+97*X^1+3*X^0) = 0
X^1
X^2+97*X+3 = 0
X^2+97*X+3 = 0
DELTA = 97^2-(1*3*4)
DELTA = 9397
DELTA > 0
X = (9397^(1/2)-97)/(1*2) or X = (-9397^(1/2)-97)/(1*2)
X = (9397^(1/2)-97)/2 or X = (-(9397^(1/2)+97))/2
X in { (-(9397^(1/2)+97))/2, (9397^(1/2)-97)/2}
