What's -9x^2+12x-4 in factored form?

Question

Please help I only have one day I asked alot of people and they cannot give me an answer. I'm smart myself and I couldn't even get it, it's a problem that is on a math poster I have to make or I fail...

Answer 1

- 9x^2 + 12x - 4

Now factorise - 9x^2 + 12x - 4.

Factoring method :

- 9x^2 + 12x - 4

- 9x^2 + 6x + 6x - 4

- 3x (3x - 2) + 2 (3x - 2)

(3x - 2)( - 3x + 2).
