Simplifying 5n2 + 19n + -68 = 0 Reorder the terms: -68 + 19n + 5n2 = 0 Solving -68 + 19n + 5n2 = 0 Solving for variable 'n'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -13.6 + 3.8n + n2 = 0 Move the constant term to the right: Add '13.6' to each side of the equation. -13.6 + 3.8n + 13.6 + n2 = 0 + 13.6 Reorder the terms: -13.6 + 13.6 + 3.8n + n2 = 0 + 13.6 Combine like terms: -13.6 + 13.6 = 0.0 0.0 + 3.8n + n2 = 0 + 13.6 3.8n + n2 = 0 + 13.6 Combine like terms: 0 + 13.6 = 13.6 3.8n + n2 = 13.6 The n term is 3.8n. Take half its coefficient (1.9). Square it (3.61) and add it to both sides. Add '3.61' to each side of the equation. 3.8n + 3.61 + n2 = 13.6 + 3.61 Reorder the terms: 3.61 + 3.8n + n2 = 13.6 + 3.61 Combine like terms: 13.6 + 3.61 = 17.21 3.61 + 3.8n + n2 = 17.21 Factor a perfect square on the left side: (n + 1.9)(n + 1.9) = 17.21 Calculate the square root of the right side: 4.148493703 Break this problem into two subproblems by setting (n + 1.9) equal to 4.148493703 and -4.148493703.Subproblem 1
n + 1.9 = 4.148493703 Simplifying n + 1.9 = 4.148493703 Reorder the terms: 1.9 + n = 4.148493703 Solving 1.9 + n = 4.148493703 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-1.9' to each side of the equation. 1.9 + -1.9 + n = 4.148493703 + -1.9 Combine like terms: 1.9 + -1.9 = 0.0 0.0 + n = 4.148493703 + -1.9 n = 4.148493703 + -1.9 Combine like terms: 4.148493703 + -1.9 = 2.248493703 n = 2.248493703 Simplifying n = 2.248493703Subproblem 2
n + 1.9 = -4.148493703 Simplifying n + 1.9 = -4.148493703 Reorder the terms: 1.9 + n = -4.148493703 Solving 1.9 + n = -4.148493703 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-1.9' to each side of the equation. 1.9 + -1.9 + n = -4.148493703 + -1.9 Combine like terms: 1.9 + -1.9 = 0.0 0.0 + n = -4.148493703 + -1.9 n = -4.148493703 + -1.9 Combine like terms: -4.148493703 + -1.9 = -6.048493703 n = -6.048493703 Simplifying n = -6.048493703Solution
The solution to the problem is based on the solutions from the subproblems. n = {2.248493703, -6.048493703}
