Simplifying 8r2 = 19 + -12r Solving 8r2 = 19 + -12r Solving for variable 'r'. Reorder the terms: -19 + 12r + 8r2 = 19 + -12r + -19 + 12r Reorder the terms: -19 + 12r + 8r2 = 19 + -19 + -12r + 12r Combine like terms: 19 + -19 = 0 -19 + 12r + 8r2 = 0 + -12r + 12r -19 + 12r + 8r2 = -12r + 12r Combine like terms: -12r + 12r = 0 -19 + 12r + 8r2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -2.375 + 1.5r + r2 = 0 Move the constant term to the right: Add '2.375' to each side of the equation. -2.375 + 1.5r + 2.375 + r2 = 0 + 2.375 Reorder the terms: -2.375 + 2.375 + 1.5r + r2 = 0 + 2.375 Combine like terms: -2.375 + 2.375 = 0.000 0.000 + 1.5r + r2 = 0 + 2.375 1.5r + r2 = 0 + 2.375 Combine like terms: 0 + 2.375 = 2.375 1.5r + r2 = 2.375 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 = 2.375 + 0.5625 Reorder the terms: 0.5625 + 1.5r + r2 = 2.375 + 0.5625 Combine like terms: 2.375 + 0.5625 = 2.9375 0.5625 + 1.5r + r2 = 2.9375 Factor a perfect square on the left side: (r + 0.75)(r + 0.75) = 2.9375 Calculate the square root of the right side: 1.71391365 Break this problem into two subproblems by setting (r + 0.75) equal to 1.71391365 and -1.71391365.Subproblem 1
r + 0.75 = 1.71391365 Simplifying r + 0.75 = 1.71391365 Reorder the terms: 0.75 + r = 1.71391365 Solving 0.75 + r = 1.71391365 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 = 1.71391365 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + r = 1.71391365 + -0.75 r = 1.71391365 + -0.75 Combine like terms: 1.71391365 + -0.75 = 0.96391365 r = 0.96391365 Simplifying r = 0.96391365Subproblem 2
r + 0.75 = -1.71391365 Simplifying r + 0.75 = -1.71391365 Reorder the terms: 0.75 + r = -1.71391365 Solving 0.75 + r = -1.71391365 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 = -1.71391365 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + r = -1.71391365 + -0.75 r = -1.71391365 + -0.75 Combine like terms: -1.71391365 + -0.75 = -2.46391365 r = -2.46391365 Simplifying r = -2.46391365Solution
The solution to the problem is based on the solutions from the subproblems. r = {0.96391365, -2.46391365}
