For the time being, Alice is teaching that group
John is calling the other members

tìm số dư của phép chia (x+2)(x+4)(x+6)(x+8)+2012 cho đa thức x2 +10x+21 Đáp án
Ta có:
Đặt A=(x+2)(x+4)(x+6)(x+8)+2012
=(x^2+10x+16)(x^2+10x+24)+2012
Đặt y=x^2+10x+21
A=(y-5)(y+3)+2012
=y^2-2y-15+2012
=y(y-2)+1997
Mà y(y-2) chia hết cho x^2+10x+21 nên số dư là 1997
