Question

Consider the generating functions

$\begin{array}{ll} A=1+x+x^2, & B=1+2 x+4 x^4+x^5, \\ C=1-x^2+x^4, & D=1+x+x^2+x^3+\cdots, \\ E=1+x^3+x^6+x^9+\cdots, & F=1-x+x^2-x^3+x^4-\cdots . \end{array}$

In exercise given below, write each indicated expression in the form

$a_0+a_1 x+a_2 x^2+a_3 x^3+\cdots .$

If the expression is a polynomial, then compute it completely; otherwise compute it through the $x^7$ term.

Step 1

1 of 4We have to calculate the product of two expressions, $A$, and $D$:

$\begin{align*} A&=1+x+x^2\\ D&=1+x+x^2+\cdots. \end{align*}$

$A$ is a polynomial and $D$ is a generating function. We only have to calculate the first $8$ terms because $D$ isn't a polynomial.
