Read each question carefully and follow the instructions to add or subtract the given polynomials. Show all your work.
1. Add the following polynomials: (5x² + 3x - 7) + (2x² - 4x + 1)
2. Find the sum of (9a³ - 2a² + 6) and (4a³ + 5a - 3).
3. Subtract the second polynomial from the first: (8y² - 6y + 10) - (3y² + 2y - 5)
4. Calculate the difference: (7b⁴ + 2b² - 1) - (b⁴ - 3b² + 8).
5. When adding polynomials, we combine terms.
6. To subtract a polynomial, we add the of each term in the second polynomial.
7. The degree of the polynomial 3x⁵ - 2x² + 7 is .
