determine the center of the circle whose equation is x^2+y^2+8x-12y+34?

x^2+y^2+8x-12y+34 = 0

x^2+8x + y^2-12y = -34
(x^2+8x+16)+(y^2-12y+36) = -34+16+36
(x+4)^2 + (y-6)^2 = 18
...

To determine the center of the circle, we can rewrite the given equation in the standard form, which is:

(x - h)^2 + (y - k)^2 = r^2

Where (h, k) represents the center of the circle.

Let's start by completing the square for both x and y terms:

x^2 + 8x + y^2 - 12y + 34 = 0

First, we group the x and y terms separately:

(x^2 + 8x) + (y^2 - 12y) + 34 = 0

Next, we need to complete the square for x by adding (8/2)^2 = 16 to both sides of the equation, and complete the square for y by adding (-12/2)^2 = 36 to both sides:

(x^2 + 8x + 16) + (y^2 - 12y + 36) + 34 + 16 + 36 = 0

Simplifying the equation:

(x + 4)^2 + (y - 6)^2 + 86 = 0

We can see that adding 86 to both sides results in a non-zero constant on the right side. Therefore, there is no real solution for this equation, meaning this equation does not represent a circle.

Please double-check the equation and confirm it. If you have any other questions, feel free to ask.

To determine the center of the circle whose equation is given as x^2+y^2+8x-12y+34, we need to rewrite the equation in a specific form called the standard form of a circle equation.

The standard form of a circle equation is (x - h)^2 + (y - k)^2 = r^2, where (h, k) represents the center coordinates of the circle and r represents the radius.

To convert the given equation into standard form, we need to complete the square for both the x and y terms. Let's go step by step:

1. Start with the given equation: x^2 + y^2 + 8x - 12y + 34 = 0

2. Group the x terms together and the y terms together:
(x^2 + 8x) + (y^2 - 12y) + 34 = 0

3. Complete the square for the x terms:
To complete the square for x^2 + 8x, we take half of the coefficient of x (which is 8) and square it. Half of 8 is 4, and 4^2 is 16.
Add 16 to both sides of the equation:
(x^2 + 8x + 16) + (y^2 - 12y) + 34 = 16

4. Complete the square for the y terms:
To complete the square for y^2 - 12y, we take half of the coefficient of y (which is -12) and square it. Half of -12 is -6, and (-6)^2 is 36.
Add 36 to both sides of the equation:
(x^2 + 8x + 16) + (y^2 - 12y + 36) + 34 = 16 + 36

5. Simplify the equation further:
(x + 4)^2 + (y - 6)^2 + 34 = 52

6. Rearrange the equation to match the standard form:
(x + 4)^2 + (y - 6)^2 = 52 - 34
(x + 4)^2 + (y - 6)^2 = 18

Now we have successfully converted the given equation into standard form. By comparing it with the standard form (x - h)^2 + (y - k)^2 = r^2, we can determine that the coordinates of the center of the circle are (-4, 6).

Therefore, the center of the circle is (-4, 6).
