To determine which polynomials have a zero located at
, we need to find the values of
for which the polynomial equals zero.Let's analyze each polynomial:1.
- This polynomial has zeros at
and
. It does not have a zero at
.2.
- This polynomial has zeros at
and
. It has a zero at
.3.
- This polynomial has zeros at
,
, and
. It does not have a zero at
.4.
- This polynomial has zeros at
,
, and
. It has a zero at
.5.
- This polynomial has zeros at
,
,
, and
. It has a zero at
.Therefore, the polynomials that have a zero located at
are:-
-
