This is a keep sheet that can be used by Algebra 1 students and beyond. It is intended to be a refresher once students have learned how to factor (look at my Factoring Quadratics Using the Box Method and Circuit Practice for more in-depth notes and circuit worksheet).
On the front side, this keep sheet explains the general concept of factoring and shows simple GCF problems and factoring quadratic equations.
On the back, there is a basic explanation of what solving a linear equation means and how it is different from solving a quadratic equation.
Completing the square and complex solutions are not covered since this is intended mainly as an end-of-year Algebra 1 resource.
