1. Read this first

   Standard form

   y = 2x² − 12x + 10. Vertex form: y = 2(x − 3)² − 8. Factored form: y = 2(x − 1)(x − 5).

2. 1.

   Milo writes the rule for a design three ways. Which form shows its zeros without any work?

   • Vertex form
   • Standard form
   • Factored form

3. Standard form

   y = -3x² − 6x + 24. Vertex form: y = -3(x + 1)² + 27. Factored form: y = -3(x + 4)(x − 2).

4. 2.

   • Standard form
   • Factored form
   • Vertex form

5. Standard form

   y = 2x² + 12x + 10. Vertex form: y = 2(x + 3)² − 8. Factored form: y = 2(x + 5)(x + 1).

6. 3.
