Sorry I do not know. Sorry to let you down
First, we can simplify it down.
x = (-x + 6)^2
Then, you should have x - (

- 12x + 36).
Factor it to get x = 4 or 9. 4 works in the original equation but 9 does not.
The answer is either C or D hope that helped a little
Answer:
It's option B
= - 1/3 -(-5/12)
= - 1/3 +5/12
Because minus and minus is plus
- - = =
Hope it's help ^_^
