tooo solve the equation x^2 + 6x + y^2 + 8y = 52, we need to complete the square for both the x and y terms.

Starting with the x terms, we add (6/2)^2 = 9 to both sides of the equation to get:

x^2 + 6x + 9 + y^2 + 8y = 61

We can simplify the left side of the equation by factoring the perfect square trinomial:

(x + 3)^2 + y^2 + 8y = 61 + 9

Next, we complete the square for the y terms by adding (8/2)^2 = 16 to both sides of the equation:

(x + 3)^2 + y^2 + 8y + 16 = 86

We can simplify the left side of the equation by factoring the perfect square trinomial:

(x + 3)^2 + (y + 4)^2 = 86

This is the equation of a circle with center (-3,-4) and radius sqrt(86)
