Not a new thread but can someone take a moment to tell me the product of this. I know it ain't hard but my I can't handle it.

The trick to tackle these kind of problems is usually to group the powers of then and the other numbers. You then have "seperate" products and sums/differences you need to calculate. This often helps.
