9.1.6 Lesson Summary

9.1.6 • Lesson Summary

In this lesson, you learned how to:

  • Recognize perfect-square expressions written in different forms.
  • Recognize quadratic equations that have a perfect-square expression and solve the equations.

Here are the activities that helped you reach those goals:

  • 9.1.1: Equations with Quadratic Expressions on Both Sides of the Equal Sign
    • In this activity, you determined what needed to be substituted for aa in order to create a true equation.
  • 9.1.2: Recognizing Structure in Perfect-Square Expressions
    • In this activity, you multiplied binomial expressions to create perfect squares.
    • 9.1.2: Self Check
    • 9.1.2: Additional Resources
  • 9.1.3: Solving Multi Step Quadratic Equations Using Perfect Squares
    • In this activity, you solved quadratic equations using two different methods. One method involved taking the square root of both sides of the equation. The other method involved multiplying two binomials and then factoring.
    • 9.1.3: Self Check
    • 9.1.3: Additional Resources
  • 9.1.4: Explain Why an Expression Is a Perfect Square
    • In this activity, you explained why we call an expression a perfect square and you solved a factored form of a quadratic equation.

After these activities, you completed the following practice:

  • 9.1.5: Practice
