Question: Write in standard form.
Answer:
Step-by-step explanation:
You group all your terms that have a in it together.
You group all your terms that have a in it together.
You put everything that doesn't have a variable on the opposing side.
Let's begin.
Add 35 on both sides:
Group terms together that have a in it and do the same for the terms.
The neat thing here is we don't really need to do anything for the 's since
Whatever we add to one side we must add to the other.
[Side note: You are going to complete the squares for the terms using the following identity:
.
]
So we are going to add on both sides (notice the coefficient of is 2 and the coefficient of is 1).
Applying the right hand side of the identity in my side note:
The cool thing about standard form is that it tells you the center and the radius.
In this case the center is (0,-1) and the radius is 6.
Standard form of a circle is where is the center and is the radius.
