Remember that the quadratic formula is: 
.
stands for the coefficient of the first term, the one associated with the 
, 
stands for the coefficient of the second term, the one associated with 
, and 
stands for the value of the constant.
In 
, our a-value is 1, our b-value is also 1, and our c-value is also 1.
Thus, when we plug in our values into our formula, we get the answer:
Simplifying this answer using 
, we get our final answer of:
