Anyway, stuck on something here, I'll give you part of the problem below:

Code: Select all

```
3 1 4
--- + --- = -----
X+6 x-2 x(2) + 4x - 12
```

The section x(2) + 4x - 12 in the book is show factored to (x+6)(x-2)

This is done to also find the LCD.

I dont understand how it got to (x+6)(x-2)??
