Ex.9.1 Q.2

Classify the following polynomials as monomials, binomials, trinomials.

Which polynomials do not fit in any of these three categories:

1. x + y,

2. 1000,

3. x + x² + x³ + x⁴,

4. 7 + y + 5x,

5. 2y – 3y²,

6. 2y - 3y + 4y,

7. 5x – 4y + 3xy,

8. 4z – 15z²,

9. ab + bc + cd + da,

10. pqr,

11. p² q + pq²,

12. 2p + 2q

1. Since x + y contains two terms. Therefore, it is binomial.

2. Since 1000 contains one term. Therefore, it is monomial.

3. Since x + x² + x³ + x⁴ contains four terms. Therefore, it is a polynomial and it does not fit in above three categories.

4. Since 7 + y + 5x contains three terms. Therefore, it is trinomial.

5. Since 2y – 3y² contains two terms. Therefore, it is binomial.

6. Since 2y – 3y² + 4y³ contains three terms. Therefore, it is trinomial.

7. Since 5x – 4y + 3xy contains three terms. Therefore, it is trinomial.

8. Since 4x - 15z² contains two terms. Therefore, it is binomial.

9. Since ab + bc + cd + da contains four terms. Therefore, it is a polynomial and it does not fit in above three categories.

10. Since pqr contains one terms. Therefore, it is monomial.

11. Since p² q + pq² contains two terms. Therefore, it is binomial.

12. Since 2p + 2q contains two terms. Therefore, it is binomial.
