The Quadratics Unit Involves; Factoring, writing, and solving quadratic equations. Factoring types: Greatest Common Factor (GCF) Difference of Two Squares Sum or Difference of Perfect Cubes Factor by Grouping and Trinomial Factoring All of the methods are used to solve quadratic equations except sum or difference of cubes (we use these to solve polynomial functions in a later unit) Generally, quadratic equations are written in two ways; Standard form y = ax2 + bx + c or Vertex form y = a(x - h)2 + k
When it comes to solving quadratics, we have four methods; 1) Factoring 2) Complete the Square 3) Graphing and 4) The quadratic formula
The quadratic formula is the only method that will solve all quadratic equations. If you only learn one method, this is the one!
