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

Answer 1

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 polynomial.

48w7 + 30w4 (1 point)

6w4(8w3 + 5)*
6w3(8w4 + 5w)
w4(48w3 + 30)
6(8w7 + 5w4)

7. What is a simpler form of each product?

(2x – 6)2 (1 point)

4x2 – 24x + 36*
4x2 – 8x + 36
4x2 + 36
4x2 – 12x + 36

9. What is a simpler form of the following expressions?

(j + 7)(j – 7) (1 point)

j2 + 14j – 49
j2 – 14j – 49
j2 + 14j – 49
j2 – 49*

10. What is a simpler form of the following expressions?

(7p – 8)(7p + 8) (1 point)

49p2 + 112p + 64
49p2 – 112p – 64
49p2 + 64
49p2 – 64*
