The given term is: 
Since here, the numerator i.e.
cannot be factorized.
SO, the only excluded value is found on the basis of the denominator. The denominator should not be equal to 0, otherwise, the fraction will turn out to be zero.
SO, if y
-4, then denominator will not be zero.
Therefore, the excluded value is -4
