Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 β 4x + 8x^2) + (β6 + 2x β 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 β 5 β 7x^2) β (β2 + 6x^2 β 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by β1. 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.
