We want to get 0 on the right, so we add  
to both sides:




The quadratic formula is stated this war:

If we have the equation:



then its solution is



In this equation, we have:



so , , 













Factor  out of the top:



Cancel the 2 into the 6, getting 3:



So the final answer is:



which is really two separate solutions:

 and
