Simplifying 4r2 + 11 = 9r Reorder the terms: 11 + 4r2 = 9r Solving 11 + 4r2 = 9r Solving for variable 'r'. Reorder the terms: 11 + -9r + 4r2 = 9r + -9r Combine like terms: 9r + -9r = 0 11 + -9r + 4r2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 2.75 + -2.25r + r2 = 0 Move the constant term to the right: Add '-2.75' to each side of the equation. 2.75 + -2.25r + -2.75 + r2 = 0 + -2.75 Reorder the terms: 2.75 + -2.75 + -2.25r + r2 = 0 + -2.75 Combine like terms: 2.75 + -2.75 = 0.00 0.00 + -2.25r + r2 = 0 + -2.75 -2.25r + r2 = 0 + -2.75 Combine like terms: 0 + -2.75 = -2.75 -2.25r + r2 = -2.75 The r term is -2.25r. Take half its coefficient (-1.125). Square it (1.265625) and add it to both sides. Add '1.265625' to each side of the equation. -2.25r + 1.265625 + r2 = -2.75 + 1.265625 Reorder the terms: 1.265625 + -2.25r + r2 = -2.75 + 1.265625 Combine like terms: -2.75 + 1.265625 = -1.484375 1.265625 + -2.25r + r2 = -1.484375 Factor a perfect square on the left side: (r + -1.125)(r + -1.125) = -1.484375 Can't calculate square root of the right side. The solution to this equation could not be determined.
