Simplifying r2 + -6r + 25 = 0 Reorder the terms: 25 + -6r + r2 = 0 Solving 25 + -6r + 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 + -6r + -25 + r2 = 0 + -25 Reorder the terms: 25 + -25 + -6r + r2 = 0 + -25 Combine like terms: 25 + -25 = 0 0 + -6r + r2 = 0 + -25 -6r + r2 = 0 + -25 Combine like terms: 0 + -25 = -25 -6r + r2 = -25 The r term is -6r. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6r + 9 + r2 = -25 + 9 Reorder the terms: 9 + -6r + r2 = -25 + 9 Combine like terms: -25 + 9 = -16 9 + -6r + r2 = -16 Factor a perfect square on the left side: (r + -3)(r + -3) = -16 Can't calculate square root of the right side. The solution to this equation could not be determined.
