第一個答中有獎

(x - a) = x - a/ Q: q$ { J5 H7 q* d* S6 z
(x - a) (x - b) = x^2 – ax – bx + ab+ X3 w. d- n. e$ |+ C5 O0 w; ?
(x - a) (x - b) (x – c) = x^3 – ax^2 – bx^2 – cx^2 + abx + acx + bcx - abc9 z0 g3 T6 b- ^( U0 N9 O( h
(x - a) (x - b) (x – c) (x - d) = x^4 – ax^3 – bx^3 – cx^3 – abx^2……………….. +abcd1 k( t% }# ]5 c" f% w- B( m
如此種推，
(x-a) (x-b) (x-c) (x-d) (x-e)……..(x-z) = ???
