Answer:

(x + 12)² + (y + 32)² = 1031  

Step-by-step explanation:

137 + 64y = -y² - x² - 24x

Arrange the terms in descending powers of x and y.

x² + 24x  + y² + 64y = -137

Complete the squares  for x and y

(x² + 24x  + 144) + (y² + 64y + 1024) = -137 + 144 + 1024

Write the equation as the  squares of binomials of x and y

(x + 12)² + (y + 32)² = 1031

This is the equation of a circle with centre at (-12, -32) and radius r = √1031.
