Answer 1

Answer:

3x2-12x+9

Step-by-step explanation:

x2-4x+3

x2-1x-3x+3

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

(x-1)(x-3)

x=1,3

Answer 2

Hola mate ! Here is your answer:

Solution:

${3x}^{2} - 12x + 9 \\ = 3 {x}^{2} - 3x - 9x + 9$

$= 3x(x - 1) - 9(x - 1)$

$(3x - 9)(x - 1) = 0$

$x = 3 \: \: or \: \: x = 1$

Hope it helps!
