D( x )
3*(x-8) = 0
3*(x-8) = 0
3*(x-8) = 0
x-8 = 0 // + 8
x = 8
x in (-oo:8) U (8:+oo)
2/(3*(x-8)) = 18 // - 18
2/(3*(x-8))-18 = 0
2/(3*(x-8))+(-18*3*(x-8))/(3*(x-8)) = 0
2-18*3*(x-8) = 0
434-54*x = 0
(434-54*x)/(3*(x-8)) = 0
(434-54*x)/(3*(x-8)) = 0 // * 3*(x-8)
434-54*x = 0
434-54*x = 0 // - 434
-54*x = -434 // : -54
x = -434/(-54)
x = 217/27
x = 217/27
