Simplifying 4r2 + -1r + 1 = 0 Reorder the terms: 1 + -1r + 4r2 = 0 Solving 1 + -1r + 4r2 = 0 Solving for variable 'r'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 0.25 + -0.25r + r2 = 0 Move the constant term to the right: Add '-0.25' to each side of the equation. 0.25 + -0.25r + -0.25 + r2 = 0 + -0.25 Reorder the terms: 0.25 + -0.25 + -0.25r + r2 = 0 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + -0.25r + r2 = 0 + -0.25 -0.25r + r2 = 0 + -0.25 Combine like terms: 0 + -0.25 = -0.25 -0.25r + r2 = -0.25 The r term is -0.25r. Take half its coefficient (-0.125). Square it (0.015625) and add it to both sides. Add '0.015625' to each side of the equation. -0.25r + 0.015625 + r2 = -0.25 + 0.015625 Reorder the terms: 0.015625 + -0.25r + r2 = -0.25 + 0.015625 Combine like terms: -0.25 + 0.015625 = -0.234375 0.015625 + -0.25r + r2 = -0.234375 Factor a perfect square on the left side: (r + -0.125)(r + -0.125) = -0.234375 Can't calculate square root of the right side. The solution to this equation could not be determined.
