The set {0, 2, 5} is under addition, as is illustrated by the fact that adding 2 and 5 results in 7, which is not included in the set. The set of all integers is closed under addition, as is illustrated by the fact that adding -20 and 6 result in -14, which is in the set. The set of all polynomials is under addition, which is illustrated by the fact that adding 3x2 − 2 and 7x4 + 4x results in 7x4 + 3x2 + 4x − 2, which is in the set.

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.
