Simplifying r2 + 2r + 25 = 0 Reorder the terms: 25 + 2r + r2 = 0 Solving 25 + 2r + r2 = 0 Solving for variable 'r'. Begin completing the square. Move the constant term to the right: Add '-25' to each side of the equation. 25 + 2r + -25 + r2 = 0 + -25 Reorder the terms: 25 + -25 + 2r + r2 = 0 + -25 Combine like terms: 25 + -25 = 0 0 + 2r + r2 = 0 + -25 2r + r2 = 0 + -25 Combine like terms: 0 + -25 = -25 2r + r2 = -25 The r term is 2r. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2r + 1 + r2 = -25 + 1 Reorder the terms: 1 + 2r + r2 = -25 + 1 Combine like terms: -25 + 1 = -24 1 + 2r + r2 = -24 Factor a perfect square on the left side: (r + 1)(r + 1) = -24 Can't calculate square root of the right side. The solution to this equation could not be determined.
