Answer:

[tex]\frac{4(x + 2)}{3(x - 7)}[/tex]

Step-by-step explanation:

Hello!

We can simplify this by factoring, and cross reducing.

Simplify

  • [tex]\frac{12}{x^2 - 49} * \frac{x^2 + 9x + 14}{9}[/tex]
  • [tex]\frac{12}{(x+7)(x - 7)} * \frac{(x + 2)(x + 7)}{9}[/tex]
  • [tex]\frac{12(x + 2)}{9(x - 7)}[/tex]
  • [tex]\frac{4(x + 2)}{3(x - 7)}[/tex]

The final simplified form is [tex]\frac{4(x + 2)}{3(x - 7)}[/tex]
