Classify the foll

(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
