1/(a-b)(a-c) + 1/(c-a)(c-b) + 1/(b-a)(b-c)
Is there a way to simplify this? If I start multiplying out everything to get the LCD my final answer will be huge.
The Attempt at a Solution
As I said, without somehow simplifying it at the start I can multiply out, get the LCD, and end up with a very long answer. Thanks.
