2. Classify the following polynomials as monomials, binomials, trinomials. Which polynomials do not fit in any of these three categories:
Ans. (i) Since 
contains two terms. Therefore it is binomial.
(ii) Since 1000 contains one terms. Therefore it is monomial.
(iii) Since 
contains four terms. Therefore it is a polynomial and it does not fit in above three categories.
(iv) Since
contains three terms. Therefore it is trinomial.
(v) Since 
contains two terms. Therefore it is binomial.
(vi) Since
contains three terms. Therefore it is trinomial.
(vii) Since 
contains three terms. Therefore it is trinomial.
(viii) Since 4z-15z2contains two terms. Therefore it is binomial.
(ix) Since 
contains four terms. Therefore it is a polynomial and it does not fit in above three categories.
(x) Since 
contains one terms. Therefore it is monomial.
(xi) Since 
contains two terms. Therefore it is binomial.
(xii) Since contains two terms. Therefore it is binomial.
