Polynomials, roots and the factor theorem

A polynomial in xxx is an expression built from powers of xxx, such as 3x3−2x+53x^3-2x+53x3−2x+5. A root is a value of xxx that makes the polynomial 0, and a factor is an expression that divides it exactly.

Step-by-step lessons covering Edexcel AS Level Maths Algebraic Methods for AS Level Maths. Each lesson breaks down 7.1 Algebraic Fractions, 7.2 Dividing Polynomials, 7.3 The Factor Theorem, 7.4 Mathematical Proof, and 7.5 Methods of Proof, then works through exam-style questions in Paper 1 and Paper 2 format. Build fluency in the core algebra, surds and trigonometry topics early, since they underpin the calculus, statistics and mechanics content that follows.
