$4z^{4}+0z^{3}+0z^{2}+11z+0z^{0}$
$11z+4z^{4}$ 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 $0z^{0}$: $...=4z^{4}+0z^{3}+0z^{2}+11z+0z^{0}$
