Answer
$4z^{4}+0z^{3}+0z^{2}+11z+0z^{0}$
Work Step by Step
$11z+4z^{4}$
First, rewrite this expression by putting $4z^{4}$ first, since we have to write this polynomial in descending order:
$11z+4z^{4}=4z^{4}+11z=...$
Insert a missing term of $0z^{3}$:
$...=4z^{4}+0z^{3}+11z=...$
Insert a missing term of $0z^{2}$:
$...=4z^{4}+0z^{3}+0z^{2}+11z=...$
Finally, insert a missing term of $0z^{0}$:
$...=4z^{4}+0z^{3}+0z^{2}+11z+0z^{0}$
