Square both sides:





Get 0 on the right and left side in descending
order:



Divide every term on both sides by 12



Factor the left side:



Use the zero-factor property:



Checking  in original:







False, so -2/3 is not a solution.

Checking  in original:







True, so the only solution is x=1.
So none of the answers you listed are
correct because they all allow something
other than 1 to be a solution.
