w in (-oo:-3) U (-3:1) U (1:+oo)
(w-7)/(w-1) = (w+4)/(w+3)+1 // - (w+4)/(w+3)+1
(w-7)/(w-1)-((w+4)/(w+3))-1 = 0
(w-7)/(w-1)+(-1*(w+4))/(w+3)-1 = 0
((w-7)*(w+3))/((w-1)*(w+3))+(-1*(w+4)*(w-1))/((w-1)*(w+3))+(-1*(w-1)*(w+3))/((w-1)*(w+3)) = 0
(w-7)*(w+3)-1*(w+4)*(w-1)-1*(w-1)*(w+3) = 0

DELTA = 9^2-(1*4*14)
DELTA = 25
DELTA > 0
w = (25^(1/2)-9)/(1*2) or w = (-25^(1/2)-9)/(1*2)
w = -2 or w = -7
-1*(w+7)*(w+2) = 0
(-1*(w+7)*(w+2))/((w-1)*(w+3)) = 0
