Question

11 Factorise:
$1 - 6x + 9 {x}^{2}$


​

Answer 1

Step-by-step explanation:

9x²-6x+1

9x²-3x-3x+1

3x(3x-1)-1(3x-1)

(3x-1)(3x-1)

Answer 2

Answer:

(3x - 1) × (3x - 1)

Step-by-step explanation:

1 - 6x + 9x²=9x² - 6x + 1 ........writing it in correct order

= (3x)² - 2 × (3x) × (1) + (1)² .......using the identity (a-b)²=a²-2ab+b²

= (3x - 1)²

= (3x - 1) × (3x - 1)
