# Classify the following polynomials as monomials, binomials, trinomials. Which polynomials do not fit in any category?(i) x+y(ii) 1000(iii) x+x2+x3+x4(iv)7+a+5b(v) 2b-3b2(vi) 2y-3y2+4y3(vii) 5x-4y+3x(viii) 4a-15a2(ix) xy+yz+zt+tx(x) pqr(xi) p2q+pq2(xii) 2p+2q

(i) x+y

This expression contains two terms x and y

So, it is called ‘Binomial’

(ii) 1000

It contains one term 1000

So, it is called monomial

(iii) x+x2+x3+x4

It contains four terms

So, it is not a monomial, binomial and trinomial

(iv)7+a+5b

It contains three terms

So, it is called trinomial

(v) 2b-3b2

It contains two terms

So, it is called binomial

(vi) 2y-3y2+4y3

It contains three terms

So, it is called trinomial

(vii) 5x-4y+3x

8x – 4y

It contains two terms

So, it is called binomial

(viii) 4a-15a2

It contains two terms

So, it is called binomial

(ix) xy+yz+zt+tx

It contains four terms

So, it is not a monomial, binomial and trinomial

(x) pqr

It contains one term

So, it is called monomial

(xi) p2q+pq2

It contains two terms

So, it is called binomial

(xii) 2p+2q

It contains two terms

So, it is called monomial
