1/w-3-2/33w-9=1/3w-9

Solution for 1/w-3-2/33w-9=1/3w-9 equation:

D( w )

w = 0

w = 0

w = 0

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

1/w-((2/33)*w)-9-3 = (1/3)*w-9 // - (1/3)*w-9

1/w-((2/33)*w)-((1/3)*w)-9-3+9 = 0

(-2/33)*w+(-1/3)*w+1/w-9-3+9 = 0

1*w^-1-13/33*w^1-3*w^0 = 0

(1*w^0-13/33*w^2-3*w^1)/(w^1) = 0 // * w^2

w^1*(1*w^0-13/33*w^2-3*w^1) = 0

w^1

(-13/33)*w^2-3*w+1 = 0

(-13/33)*w^2-3*w+1 = 0

DELTA = (-3)^2-(1*4*(-13/33))

DELTA = 349/33

DELTA > 0

w = ((349/33)^(1/2)+3)/(2*(-13/33)) or w = (3-(349/33)^(1/2))/(2*(-13/33))

w = -33/26*((349/33)^(1/2)+3) or w = -33/26*(3-(349/33)^(1/2))

w in { -33/26*((349/33)^(1/2)+3), -33/26*(3-(349/33)^(1/2))} 

w in { -33/26*((349/33)^(1/2)+3), -33/26*(3-(349/33)^(1/2)) }
