Completing the square is a method used to solve a quadratic equation by changing the shape of the equation so that the left side is a perfect square trinomial. The following equation makes more sense to solve it complete squares: x² + 20x = 52 We have then: x² + 20x + (10) ^ 2 = 52 + 100 (x + 10) ² = 152 Answer: The most sense to solve by completing the square is for: B) x² + 20x = 52
