Final answer:
The polynomial 9a^2-25b^2 has a degree of 2 and 2 terms. Hence the correct answer is option A
Step-by-step explanation:
The polynomial 9a^2-25b^2 has a degree of 2 because the highest exponent in the polynomial is 2. It has 2 terms because there are 2 separate expressions being subtracted.
The degree of a polynomial is determined by the highest exponent in the polynomial. In this case, the highest exponent is 2, so the polynomial has a degree of 2.
The number of terms in a polynomial is determined by the number of separate expressions being added or subtracted. In this case, there are 2 separate expressions being subtracted, so the polynomial has 2 terms.
Hence the correct answer is option A
