Answer:

x^4+x^3(a+b+c+d)+x^2(ab+bc+ac+bd+cd+ad)+x(abc+abd+acd+bcd)+abcd

Step-by-step explanation:

(x+a)(x+b)(x+c)(x+d)=(x^2+(a+b)x+ab)(x^2+(c+d)x+cd)

                                           =(x^2+ax+bx+ab)(x^2+cx+dx+cd)                            =x^4+cx^3+dx^3+cdx^2+ax^3+acx^2+adx^2+acdx+bx^3+bcx^2+bdx^2+bcdx+abx^2+abcx+abdx+abcd

=x^4+x^3(a+b+c+d)+x^2(ab+bc+ac+bd+cd+ad)+x(abc+abd+acd+bcd)+abcd
