Algebraic Identities: Class 8 Mathematics Worksheet

Algebraic identities are rules that are true for every value, such as (a + b)² = a² + 2ab + b² and a² − b² = (a + b)(a − b). Learners use them to expand brackets, factorise expressions like x² + 8x + 15 and even work out 998² quickly as (1000 − 2)². The paper opens with six multiple choice questions, follows with fill in the blanks and totals 15 marks.
