Full solution

Q. Factorise\newlinex2−9 x^{2}-9
  1. Recognize as difference of squares: Recognize that x2−9x^2 - 9 is a difference of squares.\newlinex2−9=(x)2−(3)2x^2 - 9 = (x)^2 - (3)^2
  2. Apply formula: Apply the difference of squares formula: a2−b2=(a+b)(a−b)a^2 - b^2 = (a + b)(a - b). (x2−9)=(x+3)(x−3)(x^2 - 9) = (x + 3)(x - 3)
