1. Completing the Square

2.  There is another way to find the minimum or maximum values of quadratic functions.

3. Example: Find the minimum or maximum value.

4. Now find the vertex… Find the y-value firstNow give the vertex.

5. Example: Find the minimum or maximum value.

6. Now find the vertex.

7. Completing the Square  The process of making a quadratic expression into a perfect square by adding half the coefficient of the x term squared is called completing the square.

8. Completing the square  Process by which you force a quadratic expression to factor 

9.  We use completing the square in order to find vertex form of a quadratic.

10. Complete the square to find the vertex form. Then find the vertex, los, and max/min.

18. Factoring IB Notation → Factorisation

19. GCF  Greatest Common Factor  ALWAYS check to see if there is a common factor in each term 1st.  If so, factor it out.

20. Factor and identify the GCF.

25. Trinomial Factoring x² coefficient is 1.

26. Factorise (IB Notation)

27. Factorise

31. Trinomial Factoring x² coefficient is NOT1.

32. Factorise
