The goal of Factoring quadratics is to

• Get factored form, like (x + __)(x + __) , so then we can use the Zero Product Property to get the solutions.

• Get standard form, like x² + __x + __, to be able to get the solutions

• Get factored form, like (x + __)(x + __) , so then we can use the Zero Product Property to find the vertex.

• Get standard form, like x² + __x + __, to be able to find the vertex
