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).PreviousLesson-2.1.6- Factorise expressions of the form: ??? ax + bx + kay + kby ??? a^2 x^2 ??? b^2 y^2 ??? a^2 + 2ab + b2 ??? ax^2 + bx + c ??? ax^3 + bx2 + cx .Next
