Algebraic Manipulation & Factorization: Class 9 Mathematics Worksheet

Expanding and factorising are two directions of the same skill: (x + 3)(x + 2) expands to x² + 5x + 6, and x² − 9 factorises as a difference of two squares into (x − 3)(x + 3). Class 9 students expand, factorise, simplify like terms and find common factors in multiple-choice questions, each with four options, out of 15.
