See the entire simplification process below:

First, factor the denominator:

$(g - 9)/((g - 9)(g + 9))$

Now, cancel the like terms in the numerator and denominator:

$color(red)(cancel(color(black)((g - 9))))/(color(red)(cancel(color(black)((g - 9))))(g + 9))$

$1/(g + 9)$

How do you simplify (g-9)/(g^2-81)(g-9)/(g^2-81)?
