Solution for -22/4-x=-11/x equation: 


D( x )

x = 0

x = 0

x = 0

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

-x-22/4 = -11/x // + -11/x

-x-(-11/x)-22/4 = 0

11*x^-1-x-22/4 = 0

11*x^-1-1*x^1-11/2*x^0 = 0

(11*x^0-1*x^2-11/2*x^1)/(x^1) = 0 // * x^2

x^1*(11*x^0-1*x^2-11/2*x^1) = 0

x^1

(-11/2)*x-x^2+11 = 0

(-11/2)*x-x^2+11 = 0

DELTA = (-11/2)^2-(-1*4*11)

DELTA = 297/4

DELTA > 0

x = ((297/4)^(1/2)-(-11/2))/(-1*2) or x = (-(-11/2)-(297/4)^(1/2))/(-1*2)

x = ((297/4)^(1/2)+11/2)/(-2) or x = (11/2-(297/4)^(1/2))/(-2)

x in { ((297/4)^(1/2)+11/2)/(-2), (11/2-(297/4)^(1/2))/(-2)} 

x in { ((297/4)^(1/2)+11/2)/(-2), (11/2-(297/4)^(1/2))/(-2) }
