B. Subtract polynomials: (3x – 5 – 7x2) – (–2 + 6x2 – 5x)
Step 1: Rewrite the polynomials without the parentheses. Remember to multiply each term in the second parentheses by –1. 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)
