Question

Two trinomials are multiplied together. If the degree of the first trinomial is 4, what must the degree of the second trinomial be in order to have a product whose degree is 8?

Answer 1

the degree of the 2nd can be found by using the index law for multiplication

if you multiply the leading terms

\[x^4 \times x^? = x^8\]
