How to Put rational expressions in lowest terms

Putting a rational expression in its lowest terms (also called "reduction") is a bit tricky, but it becomes very easy once you know a few tricks. This video demonstrates the above mentioned topic by using four unsolved examples, the solutions to which are essentially obtained by using the same techniques, however the way in which they are applied is a bit different. In the first example the term to be reduced consists only of single termed expressions, the second example depicts reduction of simple polynomials, the third deals with the reduction of a fractional term which has 2nd degree polynomials in the denominator as well as the numerator, while the last example consists a "tricky" type of term.
