Answer 1

it's degree is 4...

hope this helps

Answer 2

Answer:

The degree of this polynomial is 4.

Step-by-step explanation:

$\text{The polynomial   (x^2+9)(5-x^2) }\\\\= 5x^2 - x^4 + 45 - 9x^2\\\\= -x^4 - 4x^2 + 45\\\\\text{By multiplying...}$

So, Since degree of a polynomial is the highest power of it, the highest power for the above expanded polynomial is 4. Thus, the degree of this polynomial is 4.
