2. Use addition and subtraction to simplify the following polynomials. (7 points)
a. Add polynomials: (3 β 4x + 8x2) + (β6 + 2x β 5x2)
Step 1: Rewrite the polynomials without the parentheses. (1 point)
Step 2: Write the polynomial in descending order and use parentheses around like terms. (1 point)
Step 3: Add the like terms identified in Step 2 to simplify the polynomial. (1 point)
b. Subtract polynomials: (3x β 5 β 7x2) β (β2 + 6x2 β 5x)
Step 1: Rewrite the polynomials without the parentheses. Remember to multiply each term in the second parentheses by β1. Show your work. (2 points)
Step 2: Write the polynomial in descending order and use parentheses around like terms. (1 point)
Step 3: Add the like terms identified in Step 2 to simplify the polynomial. (1 point)
