Prefabricated homes are houses whose sections are made in a factory. These sections are then shipped and assembled at the building site. A benefit of prefabricated homes is that most of the construction occurs in a controlled environment, such as a factory, that is protected from the weather and other elements. Another benefit is that the homes’ sections are standard shapes and sizes, which makes it easy to manufacture and assemble such homes in large quantities.

 

In this lesson you will solve quadratic equations using the quadratic formula. Just as the features of a prefab home can be customized to the specifications of a buyer, a formula is versatile and can be applied to any quadratic equation!
