Solution for 8/2w^2-2w-7/2w-2 equation: 


w in (-oo:+oo)

(8/2)*w^2-(2*w)-((7/2)*w)-2 = 0

(8/2)*w^2-2*w+(-7/2)*w-2 = 0

4*w^2-11/2*w-2 = 0

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

DELTA = 249/4

DELTA > 0

w = ((249/4)^(1/2)+11/2)/(2*4) or w = (11/2-(249/4)^(1/2))/(2*4)

w = ((249/4)^(1/2)+11/2)/8 or w = (11/2-(249/4)^(1/2))/8

w in { (11/2-(249/4)^(1/2))/8, ((249/4)^(1/2)+11/2)/8 }
