Question

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

8x + 5x3 – 5 (1 point)

5x3 + 8x – 5; cubic trinomial
8x – 5 + 5x3; not a polynomial
5x3 + 8x – 5; quadratic binomial
8x + 5x3 – 5; fourth-degree monomial

2. Simplify the sum.

(4u3 + 6u2 + 7) + (6u3 – 2u + 7) (1 point)

14 – 2u + 6u2+ 10u3
10u3 + 6u2 – 2u + 14
–2u3 – 2u2 + 6u – 14
–2u3 + 6u2 – 2u + 14

3. Simplify the difference.

(6w2 – 5w – 8) – (7w2 + 4w – 2) (1 point)

13w2 + 9w + 6
–w2 – w – 10
13w2 – w – 10
–w2 – 9w – 6

4. Factor the po
