第一個答中有獎

(x - a) = x - a* r% [* I: a6 w, S
(x - a) (x - b) = x^2 – ax – bx + ab
(x - a) (x - b) (x – c) = x^3 – ax^2 – bx^2 – cx^2 + abx + acx + bcx - abc
(x - a) (x - b) (x – c) (x - d) = x^4 – ax^3 – bx^3 – cx^3 – abx^2……………….. +abcd
如此種推，4 A/ j& w! M6 M% D i" A
(x-a) (x-b) (x-c) (x-d) (x-e)……..(x-z) = ???
