Solution for (18/w)-w=7 equation: 


D( w )

w = 0

w = 0

w = 0

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

18/w-w = 7 // - 7

18/w-w-7 = 0

18*w^-1-1*w^1-7*w^0 = 0

(18*w^0-1*w^2-7*w^1)/(w^1) = 0 // * w^2

w^1*(18*w^0-1*w^2-7*w^1) = 0

w^1

18-w^2-7*w = 0

18-w^2-7*w = 0

DELTA = (-7)^2-(-1*4*18)

DELTA = 121

DELTA > 0

w = (121^(1/2)+7)/(-1*2) or w = (7-121^(1/2))/(-1*2)

w = -9 or w = 2

w in { -9, 2} 

w in { -9, 2 }
