Hi please help me fast! I have attempted this many different ways and I can't cracked it

-9x^2 - 3x + 2 factors as -(3x - 2)(3x + 1), so x = 2/3.

Sorry that's incorrect:(

Correct answer was 1/3 you were so close!

why do you post questions if you know their answers?!?

Probably the answer key or it says that it's wrong

Use the quadratic formula to solve it.

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)
