1 Simplify x^2 +4x+3 / x+3

2 simplify x^2 -1 / x+1

3 Divide x^2 - 1 into f(x) = 2x^3 + 3x^2 + 9x + 5. Write your answer in the form given by the Division Algorithm; in other words, write your answer as: 2x^3 + 3x^2 + 9x + 5 = q(x)(x^2 - 1) + r(x) for some polynomials q(x) and r(x).

4. Factor the expression x^3 + 8y^3
