Factoring by grouping with multiple variables

The video tutorial explains the process of factoring expressions with four terms by grouping. It begins with grouping the first two terms and factoring out common elements. The same process is applied to the second group. If the factored terms do not match, the strategy is adjusted by factoring out a negative number to make the terms identical. The final step involves factoring out the common terms from both groups to reach the solution.
