第一個答中有獎

(x - a) = x - a* p- i3 `; A" u" a3 [
(x - a) (x - b) = x^2 – ax – bx + ab- p3 ?- r" N( E- P4 c8 e" Z4 ^4 n
(x - a) (x - b) (x – c) = x^3 – ax^2 – bx^2 – cx^2 + abx + acx + bcx - abc6 F o6 h. j: P F
(x - a) (x - b) (x – c) (x - d) = x^4 – ax^3 – bx^3 – cx^3 – abx^2……………….. +abcd
如此種推，
(x-a) (x-b) (x-c) (x-d) (x-e)……..(x-z) = ???
