This interactive file shows how cubic polynomials can be divided by linear factors. The first four interactive sheets generate cubic expressions and the steps in the algebraic long division method can be gradually revealed. The constant term in the cubic can be altered to show how it affects the remainder. Some of these sheets always generate factors of the cubic leading to a zero remainder. The next interactive sheet requires students to use the Remainder Theorem. The final sheet generates sets of examples of factorising cubic expressions where the Factor Theorem can be used.
