Simplifying 5r2 + 7r + -62 = -4 Reorder the terms: -62 + 7r + 5r2 = -4 Solving -62 + 7r + 5r2 = -4 Solving for variable 'r'. Reorder the terms: -62 + 4 + 7r + 5r2 = -4 + 4 Combine like terms: -62 + 4 = -58 -58 + 7r + 5r2 = -4 + 4 Combine like terms: -4 + 4 = 0 -58 + 7r + 5r2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -11.6 + 1.4r + r2 = 0 Move the constant term to the right: Add '11.6' to each side of the equation. -11.6 + 1.4r + 11.6 + r2 = 0 + 11.6 Reorder the terms: -11.6 + 11.6 + 1.4r + r2 = 0 + 11.6 Combine like terms: -11.6 + 11.6 = 0.0 0.0 + 1.4r + r2 = 0 + 11.6 1.4r + r2 = 0 + 11.6 Combine like terms: 0 + 11.6 = 11.6 1.4r + r2 = 11.6 The r term is 1.4r. Take half its coefficient (0.7). Square it (0.49) and add it to both sides. Add '0.49' to each side of the equation. 1.4r + 0.49 + r2 = 11.6 + 0.49 Reorder the terms: 0.49 + 1.4r + r2 = 11.6 + 0.49 Combine like terms: 11.6 + 0.49 = 12.09 0.49 + 1.4r + r2 = 12.09 Factor a perfect square on the left side: (r + 0.7)(r + 0.7) = 12.09 Calculate the square root of the right side: 3.47706773 Break this problem into two subproblems by setting (r + 0.7) equal to 3.47706773 and -3.47706773.Subproblem 1
r + 0.7 = 3.47706773 Simplifying r + 0.7 = 3.47706773 Reorder the terms: 0.7 + r = 3.47706773 Solving 0.7 + r = 3.47706773 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '-0.7' to each side of the equation. 0.7 + -0.7 + r = 3.47706773 + -0.7 Combine like terms: 0.7 + -0.7 = 0.0 0.0 + r = 3.47706773 + -0.7 r = 3.47706773 + -0.7 Combine like terms: 3.47706773 + -0.7 = 2.77706773 r = 2.77706773 Simplifying r = 2.77706773Subproblem 2
r + 0.7 = -3.47706773 Simplifying r + 0.7 = -3.47706773 Reorder the terms: 0.7 + r = -3.47706773 Solving 0.7 + r = -3.47706773 Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right. Add '-0.7' to each side of the equation. 0.7 + -0.7 + r = -3.47706773 + -0.7 Combine like terms: 0.7 + -0.7 = 0.0 0.0 + r = -3.47706773 + -0.7 r = -3.47706773 + -0.7 Combine like terms: -3.47706773 + -0.7 = -4.17706773 r = -4.17706773 Simplifying r = -4.17706773Solution
The solution to the problem is based on the solutions from the subproblems. r = {2.77706773, -4.17706773}
