D( y )
y+6 = 0
y-8 = 0
y+6 = 0
y+6 = 0
y+6 = 0 // - 6
y = -6
y-8 = 0
y-8 = 0
y-8 = 0 // + 8
y = 8
y in (-oo:-6) U (-6:8) U (8:+oo)
9/(y+6) = 8/(y-8) // - 8/(y-8)
9/(y+6)-(8/(y-8)) = 0
9/(y+6)-8*(y-8)^-1 = 0
9/(y+6)-8/(y-8) = 0
(9*(y-8))/((y+6)*(y-8))+(-8*(y+6))/((y+6)*(y-8)) = 0
9*(y-8)-8*(y+6) = 0
y-120 = 0
(y-120)/((y+6)*(y-8)) = 0
(y-120)/((y+6)*(y-8)) = 0 // * (y+6)*(y-8)
y-120 = 0
y-120 = 0 // + 120
y = 120
y = 120
