8.3C Factoring and Solving Quadratics when a = 1

Standard(s):

  • A.SSE.2 : Use the structure of an expression to identify and ways to rewrite it.
  • 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 taking  square roots, completing the square, the quadratic formula, and 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)
