Ex 12.2, 3 (Method 1) Factorise the expressions. (i) a𝑥^2 + b𝑥a𝑥^2 + b𝑥 = (a × 𝑥 × 𝑥) + (b × 𝑥) Taking 𝑥 common, = 𝒙 (a𝒙 + b) Ex 12.2, 3 (Method 2) Factorise the expressions. (i) a𝑥^2 + b𝑥a𝑥^2 = a × 𝑥 × 𝑥 b𝑥 = b × 𝑥 So, 𝒙 is a common factor. a𝑥^2 + b𝑥 = (a × 𝑥 × 𝑥) + (b × 𝑥) Taking 𝑥 common, = 𝑥 ((a × 𝑥) + b) = 𝒙 (a𝒙 + b)
