Question

`A(x)` is a polynomial of degree 4 and `B(x)` is a polynomial of degree 3. What is the degree of `A(4)` x `B(4)`?

Answer 1

See explanation.

Explanation:

The degree of a product of 2 polynomials is the sum of degrees of the polynomials, so here we have:

`A(x)` is a polynomial of degree `4`,
`B(x)` is a polynomial of degree `3`, so the product `A(x)xxB(x)` is a polynomial of degree `7`
