Simplifying 0 = -2r2 + 6r + -1 Reorder the terms: 0 = -1 + 6r + -2r2 Solving 0 = -1 + 6r + -2r2 Solving for variable 'r'. Combine like terms: 0 + 1 = 1 1 + -6r + 2r2 = -1 + 6r + -2r2 + 1 + -6r + 2r2 Reorder the terms: 1 + -6r + 2r2 = -1 + 1 + 6r + -6r + -2r2 + 2r2 Combine like terms: -1 + 1 = 0 1 + -6r + 2r2 = 0 + 6r + -6r + -2r2 + 2r2 1 + -6r + 2r2 = 6r + -6r + -2r2 + 2r2 Combine like terms: 6r + -6r = 0 1 + -6r + 2r2 = 0 + -2r2 + 2r2 1 + -6r + 2r2 = -2r2 + 2r2 Combine like terms: -2r2 + 2r2 = 0 1 + -6r + 2r2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 0.5 + -3r + r2 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + -3r + -0.5 + r2 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + -3r + r2 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + -3r + r2 = 0 + -0.5 -3r + r2 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 -3r + r2 = -0.5 The r term is -3r. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3r + 2.25 + r2 = -0.5 + 2.25 Reorder the terms: 2.25 + -3r + r2 = -0.5 + 2.25 Combine like terms: -0.5 + 2.25 = 1.75 2.25 + -3r + r2 = 1.75 Factor a perfect square on the left side: (r + -1.5)(r + -1.5) = 1.75 Calculate the square root of the right side: 1.322875656 Break this problem into two subproblems by setting (r + -1.5) equal to 1.322875656 and -1.322875656.Subproblem 1
r + -1.5 = 1.322875656 Simplifying r + -1.5 = 1.322875656 Reorder the terms: -1.5 + r = 1.322875656 Solving -1.5 + r = 1.322875656 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + r = 1.322875656 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + r = 1.322875656 + 1.5 r = 1.322875656 + 1.5 Combine like terms: 1.322875656 + 1.5 = 2.822875656 r = 2.822875656 Simplifying r = 2.822875656Subproblem 2
r + -1.5 = -1.322875656 Simplifying r + -1.5 = -1.322875656 Reorder the terms: -1.5 + r = -1.322875656 Solving -1.5 + r = -1.322875656 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + r = -1.322875656 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + r = -1.322875656 + 1.5 r = -1.322875656 + 1.5 Combine like terms: -1.322875656 + 1.5 = 0.177124344 r = 0.177124344 Simplifying r = 0.177124344Solution
