Simplifying 5r2 + -4r + 3 = 0 Reorder the terms: 3 + -4r + 5r2 = 0 Solving 3 + -4r + 5r2 = 0 Solving for variable 'r'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 0.6 + -0.8r + r2 = 0 Move the constant term to the right: Add '-0.6' to each side of the equation. 0.6 + -0.8r + -0.6 + r2 = 0 + -0.6 Reorder the terms: 0.6 + -0.6 + -0.8r + r2 = 0 + -0.6 Combine like terms: 0.6 + -0.6 = 0.0 0.0 + -0.8r + r2 = 0 + -0.6 -0.8r + r2 = 0 + -0.6 Combine like terms: 0 + -0.6 = -0.6 -0.8r + r2 = -0.6 The r term is -0.8r. Take half its coefficient (-0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. -0.8r + 0.16 + r2 = -0.6 + 0.16 Reorder the terms: 0.16 + -0.8r + r2 = -0.6 + 0.16 Combine like terms: -0.6 + 0.16 = -0.44 0.16 + -0.8r + r2 = -0.44 Factor a perfect square on the left side: (r + -0.4)(r + -0.4) = -0.44 Can't calculate square root of the right side. The solution to this equation could not be determined.
