Question

Factorise =
9x²-12x+3​

Answer 1

Answer:

9x²-12x+3

9x²-9x-3x+3

9x(x-1)-3(x-1)

(x-1)(9x-3)

Answer 2

Answer:

$9 {x}^{2} - 12x + 3 = 0 \\ 9 { x}^{2} - 9x - 3x + 3 = 0 \\ 9x(x - 1) - 3(x - 1) = 0 \\ (x - 1)(9x - 3) = 0 \\ x - 1 = 0 \: or \: 9x - 3 = 0 \\ x = 1 \: or \: 9x = 3 \\ x = 1 \: or \: x = \frac{3}{9} \\ x = 1 \: or \: x = \frac{1}{3}$
