Simplifying r2 + 1.5r + -20 = 0 Reorder the terms: -20 + 1.5r + r2 = 0 Solving -20 + 1.5r + r2 = 0 Solving for variable 'r'. Begin completing the square. Move the constant term to the right: Add '20' to each side of the equation. -20 + 1.5r + 20 + r2 = 0 + 20 Reorder the terms: -20 + 20 + 1.5r + r2 = 0 + 20 Combine like terms: -20 + 20 = 0 0 + 1.5r + r2 = 0 + 20 1.5r + r2 = 0 + 20 Combine like terms: 0 + 20 = 20 1.5r + r2 = 20 The r term is 1.5r. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5r + 0.5625 + r2 = 20 + 0.5625 Reorder the terms: 0.5625 + 1.5r + r2 = 20 + 0.5625 Combine like terms: 20 + 0.5625 = 20.5625 0.5625 + 1.5r + r2 = 20.5625 Factor a perfect square on the left side: (r + 0.75)(r + 0.75) = 20.5625 Calculate the square root of the right side: 4.534589287 Break this problem into two subproblems by setting (r + 0.75) equal to 4.534589287 and -4.534589287.Subproblem 1
r + 0.75 = 4.534589287 Simplifying r + 0.75 = 4.534589287 Reorder the terms: 0.75 + r = 4.534589287 Solving 0.75 + r = 4.534589287 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + r = 4.534589287 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + r = 4.534589287 + -0.75 r = 4.534589287 + -0.75 Combine like terms: 4.534589287 + -0.75 = 3.784589287 r = 3.784589287 Simplifying r = 3.784589287Subproblem 2
r + 0.75 = -4.534589287 Simplifying r + 0.75 = -4.534589287 Reorder the terms: 0.75 + r = -4.534589287 Solving 0.75 + r = -4.534589287 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + r = -4.534589287 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + r = -4.534589287 + -0.75 r = -4.534589287 + -0.75 Combine like terms: -4.534589287 + -0.75 = -5.284589287 r = -5.284589287 Simplifying r = -5.284589287Solution
