Simplify the question above

Step-by-step explanation:

1) Rewrite x² - 9 in the form a² - b² where, a = x and b = 3.

2) use difference of squares: a² - b² = ( a + b ) (a - b).

3) Factor out the common term x.

4) Cancle out x - 3 .

5) Simplify.

Therefor, the answer is 1 + 3/x.

what the question so we can you out

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
