Lesson
Lesson-2.1.4- Expand products of algebraic expressions. e.g. expand 3x(2x ??? 4y), (3x + y)(x ??? 4y). Includes products of more than two brackets, e.g. expand (x ??? 2)(x + 3)(2x + 1).

Lesson-2.1.3- Simplify expressions by collecting like terms. Simplify means give the answer in its simplest form, e.g. 2a^2 + 3ab ??? 1 + 5a^2 ??? 9ab + 4 = 7a^2 ??? 6ab + 3.PreviousLesson-2.1.5- Factorize by extracting common factors. Factorise means factorise fully, e.g. 9x^2 + 15xy = 3x(3x + 5y).Next
