Simplifying r2 + -1r + 2 = 0 Reorder the terms: 2 + -1r + r2 = 0 Solving 2 + -1r + r2 = 0 Solving for variable 'r'. Begin completing the square. Move the constant term to the right: Add '-2' to each side of the equation. 2 + -1r + -2 + r2 = 0 + -2 Reorder the terms: 2 + -2 + -1r + r2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1r + r2 = 0 + -2 -1r + r2 = 0 + -2 Combine like terms: 0 + -2 = -2 -1r + r2 = -2 The r term is -1r. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1r + 0.25 + r2 = -2 + 0.25 Reorder the terms: 0.25 + -1r + r2 = -2 + 0.25 Combine like terms: -2 + 0.25 = -1.75 0.25 + -1r + r2 = -1.75 Factor a perfect square on the left side: (r + -0.5)(r + -0.5) = -1.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
