CSEC Mathematics: Algebra — Simplifying, Expanding & Factorising

Algebra isn't harder maths. It's the same maths you already do, with letters standing in for numbers — and once you see that, the whole topic opens up. This lesson covers collecting like terms, expanding brackets, taking out a common factor, the difference of two squares, and factorising quadratics. Every line is worked out the way a marker wants to see it, so you pick up the method marks even when the final answer slips.
