Solution for 1/x+1-9/3x+3+5/2x+2 equation: 


D( x )

x = 0

x = 0

x = 0

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

(5/2)*x-((9/3)*x)+1/x+1+2+3 = 0

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

1*x^-1-1/2*x^1+6*x^0 = 0

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

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

x^1

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

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

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

DELTA = 38

DELTA > 0

x = (38^(1/2)-6)/(2*(-1/2)) or x = (-38^(1/2)-6)/(2*(-1/2))

x = 6-38^(1/2) or x = 38^(1/2)+6

x in { 6-38^(1/2), 38^(1/2)+6} 

x in { 6-38^(1/2), 38^(1/2)+6 }
