How do I change from...
  • Factored to standard?
    • multiply everything out and combine like terms
      1. multiply the parentheses first 
      2. distribute a into that answer
  • Vertex to standard?
    • multiply everything out and combine like terms
      1. square the parentheses first (times itself and FOIL)
      2. distribute the a
      3. add the k
  • Standard to factored? (or the factoring trinomials videos from a couple weeks back may be more helpful)
    • factor the polynomial
      1. split the middle term (into p and q)
      2. factor by grouping
  • Standard to Vertex?
    • a = steal it from standard
    • h = -b/2a
    • k =  plug in the h value to the standard form equation and simplify
