3 examples:


--Factoring trinomials can be used to find out how long it takes for a ball that was dropped from a top of a building, to reach a specific height in a specific time


--Factoring polynomials can be used in architecture to reduce the numbers, by factoring them, and make scaling easier.

--It could be used also for seeing how longs things take. For example if it takes three different people three different times to do some thing by themselves, you can use factoring of polynomials to see how long it will take for them to do it together. Since they are three it will be a trinomial.
