ANSWER
EXPLANATION
We use the method of completing the squares.
The equation is
We rewrite the above equation to obtain;
We divide through by 3 to obtain;
We add half the coefficient of
to both sides of the equation to get,
The right hand side is now a perfect square.
We now take square root of both sides to get;
We add -2 to both sides,
We simplify to obtain,
