Solution for w/w-3-2w/2w-3=w-5/2w^2-9w+9 equation: 


D( w )

w = 0

w = 0

w = 0

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

w/w-(((2*w)/2)*w)-3-3 = w-((5/2)*w^2)-(9*w)+9 // - w-((5/2)*w^2)-(9*w)+9

(5/2)*w^2-(((2*w)/2)*w)-w+9*w+w/w-9-3-3 = 0

(5/2)*w^2-w^2-w+9*w+w/w-9-3-3 = 0

3/2*w^2+8*w-14 = 0

DELTA = 8^2-(-14*3/2*4)

DELTA = 148

DELTA > 0

w = (148^(1/2)-8)/(3/2*2) or w = (-148^(1/2)-8)/(3/2*2)

w = (2*37^(1/2)-8)/3 or w = (-2*37^(1/2)-8)/3

w in { (-2*37^(1/2)-8)/3, (2*37^(1/2)-8)/3 }
