### dividing/ multiplying Polynomial fractions

I was wondering if you could show me how (showing the work) to do these problems:

1. divide and simplify: x^2 -9/x^2 +6x-7 / x^2 -x-6/3x+21

2.Multiply and simplify: x^2 -2x/x^2 -4 * 3x^2 -5x-2/3x^2 +x

I don’t know how this will display but #1 is a polynomial fraction divided by another and # 2 is a polynomial fraction multiplied by another. the x’s are squared (not x^(5x-2))

For worked examples, try this lesson. The first page covers exercise (2), being how to multiply rational expressions; the second page covers exercise (1), being how to divide rational expressions.
