6D:solving cubics equations

Image
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
