I have added an attachment. Could you show me the steps to solve #3. Thank you.

Division is the same as the multiplication of the inverse.

1. Inverting and multiplying cancels the (x-2)'s,

so all that's left is -7/5.

2. The second fraction is inverted. The first fraction has and (x-8)(x+8) on top.

The x-8 terms cancel, leaving the answer.

3. The 2nd fraction factors into (x+8)(x-3).

Since it is divided by x-3, the terms cancel, leaving (x+8).

Dividing the numerator of the first fraction by (x+8) gives x²-6x-9.

That is the same as (x-3)², so one (x-3) term cancels.

That leaves an x-3 in the numerator and and 8 in the denominator.

I believe it also leaves a negative sign.

With that, the answer can be seen.

4. Inverting the second fraction and multiplying cancels the (x-3) term in each fraction.

The answer has a negative sign, a 3 in the numerator, and a 2 in the denominator.
