D( x )

5.5-x = 0

5.5-x = 0

5.5-x = 0

5.5-x = 0 // - 5.5

-x = -5.5 // * -1

x = 5.5

x in (-oo:5.5) U (5.5:+oo)

(2*x^2)/(5.5-x) = 0.00000273 // - 0.00000273

(2*x^2)/(5.5-x)-0.00000273 = 0

(2*x^2)/(5.5-x)+(-0.00000273*(5.5-x))/(5.5-x) = 0

2*x^2-0.00000273*(5.5-x) = 0

2*x^2+0.00000273*x-0.000015015 = 0

2*x^2+0.00000273*x-0.000015015 = 0

2*x^2+0.00000273*x-0.000015015 = 0

DELTA = 0.00000273^2-(-0.000015015*2*4)

DELTA = 0.00012012

DELTA > 0

x = (0.00012012^(1/2)-0.00000273)/(2*2) or x = (-0.00012012^(1/2)-0.00000273)/(2*2)

x = (0.00012012^(1/2)-0.00000273)/4 or x = (-(0.00012012^(1/2)+0.00000273))/4

(x+(0.00012012^(1/2)+0.00000273)/4)*(x-((0.00012012^(1/2)-0.00000273)/4)) = 0

((x+(0.00012012^(1/2)+0.00000273)/4)*(x-((0.00012012^(1/2)-0.00000273)/4)))/(5.5-x) = 0
