Simplifying 10r2 + 5 = -9r Reorder the terms: 5 + 10r2 = -9r Solving 5 + 10r2 = -9r Solving for variable 'r'. Reorder the terms: 5 + 9r + 10r2 = -9r + 9r Combine like terms: -9r + 9r = 0 5 + 9r + 10r2 = 0 Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. 0.5 + 0.9r + r2 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + 0.9r + -0.5 + r2 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + 0.9r + r2 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + 0.9r + r2 = 0 + -0.5 0.9r + r2 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 0.9r + r2 = -0.5 The r term is 0.9r. Take half its coefficient (0.45). Square it (0.2025) and add it to both sides. Add '0.2025' to each side of the equation. 0.9r + 0.2025 + r2 = -0.5 + 0.2025 Reorder the terms: 0.2025 + 0.9r + r2 = -0.5 + 0.2025 Combine like terms: -0.5 + 0.2025 = -0.2975 0.2025 + 0.9r + r2 = -0.2975 Factor a perfect square on the left side: (r + 0.45)(r + 0.45) = -0.2975 Can't calculate square root of the right side. The solution to this equation could not be determined.
