Objectives: similar to ex 6C, we need to factorise the cubic equation and apply the Null Factor Law learned in chapter 3-Quadratics. Case 1: factors form. Use Null factor loaw Case 2: groupings- factorise the first two terms, factor out the common factor, and finally null factor law case 3: apply factor theorem, long division, cross method and finally null factor law

Here, you will learn how to factorise polynomials of degree 3 and above. In chapter 3, you've learned how to factorise quadratic equations using a variety of techniques. These were: cross method, common factors, completing the square, the quadratic equation. However, when it comes to polynomials of higher power, those strategies don't apply to it. In this exercise, we will learn about the Remainder Theorem and the Factor theorem. These two provide the foundation for factorising polynomials. You will also need to be strong in long division in the previous exercise in order to be successful in this section.

Task 1: circle patterns click here In this activity, students notice similarities and differences in a set of circles. They use this information to practice writing equations of circles that extend a given pattern or match a given set of conditions. Task 2: domain and range click here This activity will encourage student creativity while also helping them review a) function inequalities, and b) domain and range restrictions.
