with two inputs, the amp is probably a differential one. That means that one input will follow the input, and the other will invert it.

Two inputs are very handy. Not only you can build a inverting or non-inverting amplifier, but also you can set the gain. Operational amplifiers have two inputs and a very large gain. The gain is normally unstable, but with a negative feedback network you can build a very stable amplifier. Of course, op-amps have many purposes. They are the most versatile amplifiers you can find.

The other input is at the same voltage only if there is feedback involved, and the amp isn´t near clipping conditions.
