Answer 2

Answer:

Because there are two factors linear in x therefore after simplificatation the polynomial expression will come out to be a polynomial of degree 2 also known as a quadratic polynomial.

This can be done as

(x-5)(x+9) = x^2 + 4x - 45

So, the highest power of x in this polynomial expression is 2 and hence the degree.
