you can use any method (Synthetic Division, Remainder Theorem, Factor Theorem, Rational Root Theorem) to answer the following below


1.) what is the qoutient when x³ + 2x² - x - 2 is divided by x - 1?

2.) Solve for the remainder: (x³ - 3x² - 13x + 15) ÷ (x - 3).

3.) Determine the quotient and remainder if x⁴ + 6x³ + 7x² - 6x - 8 is divided by x + 7.

4.) Is x + 7 a factor of x⁴ + 6x³ + 7x² - 6x - 8. state a valid reason.​
