Question

Write the equation of the circle below in a factored form.

Answer 1

Answer:

(x + 7)² + ( y - 8)² = 158

Step-by-step explanation:

x² + 14x + y² - 16y - 45 = 0

x² + 14x + y² - 16y        = 45        

x² + 14x + 49 + y² - 16y  + 64       = 45  + 49 +64

(x² + 14x + 49) + (y² - 16y  + 64) = 158

(x + 7)² + ( y - 8)² = 158
