Subtract the polynomials: (6x3 - 4x + 2) - (2x3 - 1). enter your answer as a polynomial in descending order below, and use the caret (^) for exponents. for example, you would write as 4x^2.

[15 points]find the quotient with the restrictions. (x^2 - 2x - 3) (x^2 + 4x + 3) ÷ (x^2 + 2x - 8) (x^2 + 6x + 8)
