Hi!

Polynomial: 2a³ + 5a² + a - 2

The degree of polynomial is the monomial with the greatest exponent.

The first term 2a³, the exponent is 3. In the second term, 5a², the exponent is 2. In the third term a, the exponent is 1.

The first term got the highest exponent which is 3. So, the degree of polynomial is 3.

Answer: a. 3

(Ps. Bilangin mo lang kung ilang exponent kada term, kung ano ang pinakamataas, yun yung degree niya.)
