Use either the British Method or the Box Method to factor each quadratic equation.
Set each factor equal to zero and solve for x.
Finding Zeros by Factoring With No C
Divide out what the two terms have in common.
Set the GCF and what remains equal to zero. This creates two separate problems.
Writing Quadratic Equations From Given Zeros
You want to use the opposite signs of the given x - values to create the two sets. Once you have the factor sets you will FOIL (multiply, distribution, etc.). Finish by combing your like terms.
