we have
![y=x^(2) +6x+10](https://img.qammunity.org/2019/formulas/mathematics/high-school/x9ubhpw8sng7gqll75d1tl0rfz15z6y69s.png)
we know that
the equation in vertex form is equal to
![y=(x-h)^(2) +k\\](https://img.qammunity.org/2019/formulas/mathematics/high-school/pkwax8iaasz5y351nsrptnuwfkzuku4owt.png)
where
is the vertex
Group terms that contain the same variable, and move the constant to the opposite side of the equation
![y-10=x^(2) +6x](https://img.qammunity.org/2019/formulas/mathematics/high-school/9ou1l2cp2z99isft52e2g5l66ti7eos95f.png)
Complete the square. Remember to balance the equation by adding the same constants to each side.
![y-10+9=x^(2) +6x+9](https://img.qammunity.org/2019/formulas/mathematics/high-school/mtajfxnm75k7v4xfodjg6zzd70yani6vam.png)
![y-1=x^(2) +6x+9](https://img.qammunity.org/2019/formulas/mathematics/high-school/ebvb4spb679qimammp1adtqpbw8elawoiv.png)
Rewrite as perfect squares
![y-1=(x+3)^(2)](https://img.qammunity.org/2019/formulas/mathematics/high-school/nnmjfq771sxs0ovj1vzoittwhwt5w6wjvc.png)
![y=(x+3)^(2)+1](https://img.qammunity.org/2019/formulas/mathematics/high-school/xhtpsy0oa41i7h3e57oiyv774w58lismcu.png)
![(h,k)=(-3,1)](https://img.qammunity.org/2019/formulas/mathematics/high-school/a3gjqvmvcx0w94j2a2lujns6vvgsudmf53.png)
therefore
the answer is
the equation in vertex form is equal to
![y=(x+3)^(2)+1](https://img.qammunity.org/2019/formulas/mathematics/high-school/xhtpsy0oa41i7h3e57oiyv774w58lismcu.png)
