Classify the following polynomials as monomials, binomials, trinomials

1.	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
Answer» (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. (x) Since pqr contains one terms. Therefore it is monomial. (xi) Since p²q + pq contains two terms. Therefore it is binomial. (xii) Since 2 p + 2q contains two terms. Therefore it is binomial.
