Find the center and the radius of this equation by completing the

square.

For the values of x and y, be sure to include the "+" or "-" sign before

the number.

x2 + 4x + y2 – 20y + 100 = 0

C=( -2

10

Dr=

And solving we got:

If we subtract 100 from both sides we got:

Step-by-step explanation:

For this case we have the following equation given:

We want to find a general expression given by:

Where the center is (h.k) and the radius is r.

We can begin completing the squares of the equation given and we got:

And solving we got:

If we subtract 100 from both sides we got:

Then we can conclude that the center is:

And the radius would be:

the answers are in the images, i received 100% on this assignment. hope this !

r and t.

both are 64 degrees.
