Simplifying 2r2 + -5r + -6 = 0 Reorder the terms: -6 + -5r + 2r2 = 0 Solving -6 + -5r + 2r2 = 0 Solving for variable 'r'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -3 + -2.5r + r2 = 0 Move the constant term to the right: Add '3' to each side of the equation. -3 + -2.5r + 3 + r2 = 0 + 3 Reorder the terms: -3 + 3 + -2.5r + r2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -2.5r + r2 = 0 + 3 -2.5r + r2 = 0 + 3 Combine like terms: 0 + 3 = 3 -2.5r + r2 = 3 The r term is -2.5r. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5r + 1.5625 + r2 = 3 + 1.5625 Reorder the terms: 1.5625 + -2.5r + r2 = 3 + 1.5625 Combine like terms: 3 + 1.5625 = 4.5625 1.5625 + -2.5r + r2 = 4.5625 Factor a perfect square on the left side: (r + -1.25)(r + -1.25) = 4.5625 Calculate the square root of the right side: 2.136000936 Break this problem into two subproblems by setting (r + -1.25) equal to 2.136000936 and -2.136000936.Subproblem 1
r + -1.25 = 2.136000936 Simplifying r + -1.25 = 2.136000936 Reorder the terms: -1.25 + r = 2.136000936 Solving -1.25 + r = 2.136000936 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + r = 2.136000936 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + r = 2.136000936 + 1.25 r = 2.136000936 + 1.25 Combine like terms: 2.136000936 + 1.25 = 3.386000936 r = 3.386000936 Simplifying r = 3.386000936Subproblem 2
r + -1.25 = -2.136000936 Simplifying r + -1.25 = -2.136000936 Reorder the terms: -1.25 + r = -2.136000936 Solving -1.25 + r = -2.136000936 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + r = -2.136000936 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + r = -2.136000936 + 1.25 r = -2.136000936 + 1.25 Combine like terms: -2.136000936 + 1.25 = -0.886000936 r = -0.886000936 Simplifying r = -0.886000936Solution
