• 1.
  Simplifying Rational Expressions Involving Multiplication
  State the non-permissible values, then simplify:
  $\frac{5x^2y^3}{x^2y^2} \times \frac{9z^3x^4y^2}{15y^3z^2}$

---

• 2.
  Multiplying Rational Expressions in Factored Form
  State the non-permissible values, then simplify:
  $\frac{(x+2)}{(x-12)(x+4)} \times \frac{2(x+4)}{x(x+2)}$

---

• 3.
  Convert Expressions to Factored Form, then multiply
  State the non-permissible values, then simplify:
  
  a)

  $\frac{5x^2-15x}{30x^2-10x} \times \frac{3x^2+8x-3}{(x^2-9)}$
  
  
  b)

  $\frac{5x+20}{8x-4} \times \frac{10x-5}{(4+x)^2}$
  
  
  c)

  $\frac{(x^2+9x+8)(49x^3-x)}{(7x^2+55x-8)(x^2+x)}$
