Answer:

The answer to your question is (x + 7)² + (y - 5)² = 88

Explanation:

Equation

x² + 14x + y² - 10y = 14

Complete perfect trinomial squares

x² + 14x + (7)² + y² - 10y + (5)² = 14 + (7)² + (5)²

Simplify

x² + 14x + (7)² + y² - 10y + (5)² = 14 + 49 + 25

x² + 14x + (7)² + y² - 10y + (5)² = 88

Factor

(x + 7)² + (y - 5)² = 88 This is the equation in the form

center-radius
