Homer wants to identify the center and radius of the circle defined by the equation x² + y² - 14x +
2y - 25 = 0. He follows these steps:
Step 1: (x² – 14x) + (y2 + 2y) = 25
Step 2: (x2 – 14x + 49) + (y2 + 2y + 1) = 25
Step 3: (x - 2)2 + (y + 1)2 = 25
Step 4: The center is (7.-1), and the radius is 5.
At which step did Homer make a mistake, and what was it?
