In order to verify the values are zeros of polynomial , we must replace the variable with the given values.
If , then that given value is zero of polynomial .
(i) :
Put , we get,
.
So, is the zero of the given polynomial .
(ii) :
Put , we get,
.
So, is not the zero of the given polynomial .
(iii) :
Put , we get,
.
So, is the zero of the given polynomial .
Now put , we get,
.
So, is the zero of the given polynomial .
(iv) :
Put , we get,
.
So, is the zero of the given polynomial .
Now put , we get,
.
So, is the zero of the given polynomial .
(v) :
Put , we get,
.
So, is the zero of the given polynomial .
(vi) :
Put , we get,
.
So, is the zero of the given polynomial .
(vii) :
Put , we get,
.
So, is the zero of the given polynomial .
Now put , we get,
.
So, is not the zero of the given polynomial .
(viii) :
Put , we get,
.
So, is not the zero of the given polynomial .
