### 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:
