Question

Guided Practice

Write the polynomial in standard form. Then name the polynomial based on its degree and number of terms.

y – 7y3 + 15y8


A.
15y8 – 7y3 + y; third degree trinomial


B.
y – 7y3 + 15y8; eighth degree trinomial


C.
15y8 – 7y3 + y; eighth degree trinomial

Answer 1

C.

15y8 – 7y3 + y; eighth degree trinomial

Explanation:

To write the polynomial in standard from, the degrees of the monomials need to decrease from left to right. Reorder the monomials to get 15y8 – 7y3 + y.

The polynomial has three terms, which makes it a trinomial. The monomial with the greatest exponent is 15y8, an eighth degree term. This makes the expression an eighth degree trinomial.

Answer 2

Answer: y( 1 - 7y2 + 15y7)

Step-by-step explanation:Just put () around the 1 threw 15 and put the y out of the ()
