Identify each expression as a polynomial or not a polynomial. For each polynomial, give the degree and identify it as a monomial, binomial, trinomial, or none of these.See Example 1. 5

In Exercises 9–22, multiply the monomial and the polynomial.−4xⁿ (3x²ⁿ − 5xⁿ + 1/2 x)

In Exercises 23–34, find each product using either a horizontal or a vertical format.(x−3)(x²+2x+5)

Add or subtract, as indicated. See Example 2. (5x^2-4x+7) + (-4x^2+3x-5)

Add or subtract, as indicated. See Example 2. (3m^5-3m^2+4) + (-2m^3-m^2+6)

In Exercises 23–34, find each product using either a horizontal or a vertical format.(x−1)(x²+x+1)

In Exercises 15–32, multiply or divide as indicated. (x^2−4)/(x−2) ÷ (x+2)/(4x−8)

In Exercises 15–58, find each product. (2x−5)(7x+2)

In Exercises 15–32, multiply or divide as indicated. (x^2+x)/(x^2−4) ÷ (x^2−1)/(x^2+5x+6)

In Exercises 15–58, find each product. (7x^2−2)(3x^2−5)

In Exercises 15–58, find each product. (7x^3+5)(x^2−2)

Find each product. See Examples 3–5. (5m-6)(3m+4)

In Exercises 15–32, multiply or divide as indicated. (x^2−4)/(x^2+3x−10) ÷ (x^2+5x+6)/(x^2+8x+15)

Find each product. See Examples 3–5. x^2(3x-2)(5x+1)

In Exercises 15–32, multiply or divide as indicated. (x^3−25x)/4x^2 ⋅ (2x^2−2)/(x^2−6x+5) ÷ (x^2+5x)/(7x+7)
