8.3B Solving Quadratic Equations a=1

Standard(s):

  • A.SSE.3.a.: Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression. Factor a quadratic expression to reveal the zeros of the function it defines.
  • A.REI.4b.:  Solve quadratic equations in one variable. Solve quadratic equations by inspection factoring as appropriate to the initial form of the equation.  


Essential Question:

  • Why structure expressions in different ways?
  • How are quadratic functions used to model, analyze, and interpret mathematical relationships?
  • What are the different ways to solve a quadratic equation, and when is each appropriate?
  • How can analytic and graphical methods be used to support each other in the solution of a problem?

Learning Target:

  • I can identify a greatest common factor. (Blooms Level: Applying)
  • I can factor a greatest common factor out of a polynomial. (Blooms Level: Applying)
  • I can identify common terms when factoring. (Blooms Level: Remembering)
  • I can solve a quadratic equation by factoring.(Blooms Level: Applying)
