Classify the following polynomials as monomials, binomials, trinomials. Which polynomials do not fit in any of these three categories: x + y, 1000, x+x²+x³+ x⁴, 7+y+5x, 2y-3y², 2y-3y²+4y³, 5x-4y+3xy, 4z-15z², ab+bc+cd+da, pqr, p²q + pq², 2p+2q

(i) Since x + y contains two terms. Therefore it is binomial.
(ii) Since 1000 contains one terms. Therefore it is monomial.
(iii) Since X+x²+x³+x⁴ contains four terms. Therefore it is a polynomial and
it does not fit in above three categories.
(iv) Since 7+y+5x contains three terms. Therefore it is trinomial.
(v) Since 2y-3y² contains two terms. Therefore it is binomial.
(vi) Since 2y-3y²+4y³ contains three terms. Therefore it is trinomial.
(vii) Since 5x-4y+3xy contains three terms. Therefore it is trinomial.
(viii) Since 4x-15z² contains two terms. Therefore it is binomial.
(ix) Since ab+bc+cd+da contains four terms. Therefore it is a polynomial
and it does not fit in above three categories.
