Simplifying r2 + -1r + 7 = 0 Reorder the terms: 7 + -1r + r2 = 0 Solving 7 + -1r + r2 = 0 Solving for variable 'r'. Begin completing the square. Move the constant term to the right: Add '-7' to each side of the equation. 7 + -1r + -7 + r2 = 0 + -7 Reorder the terms: 7 + -7 + -1r + r2 = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -1r + r2 = 0 + -7 -1r + r2 = 0 + -7 Combine like terms: 0 + -7 = -7 -1r + r2 = -7 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 = -7 + 0.25 Reorder the terms: 0.25 + -1r + r2 = -7 + 0.25 Combine like terms: -7 + 0.25 = -6.75 0.25 + -1r + r2 = -6.75 Factor a perfect square on the left side: (r + -0.5)(r + -0.5) = -6.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
