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 A Level Maths Algebraic Methods for A 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, Paper 2 and Paper 3 format. Build fluency with the core pure algebra and calculus toolkit early, since almost every mechanics and statistics topic on the course depends on it.
