Answer:
and 
.
Step-by-step explanation:
Start by adding 1 to both sides of this equation.
.
The square of what number or numbers will lead to the number "1"? It turns out that not only 
, but 
as well. In other words, the value 
can be either 1 or -1. Either way, the equation is still going to hold. That's the reason why there are two solutions to this equation.
Consider the case when 
. Add 10 to both sides of the equation. 
.
Now, consider the case when 
. Again, add 10 to both sides of the equation, 
.
Order the two solutions in an increasing order:
- ,
- .
ANSWER
(-1,2)
EXPLANATION
The given quadratic expression is:
The coefficient of the quadratic term is already 1.
So we add and subtract the square of half the coefficient of x.
We factor the first three terms to obtain
This is now in the form:
where (h,k) which is equal to (-1,2) is the vertex.
