Simplifying 10n2 = 8n + 7 Reorder the terms: 10n2 = 7 + 8n Solving 10n2 = 7 + 8n Solving for variable 'n'. Reorder the terms: -7 + -8n + 10n2 = 7 + 8n + -7 + -8n Reorder the terms: -7 + -8n + 10n2 = 7 + -7 + 8n + -8n Combine like terms: 7 + -7 = 0 -7 + -8n + 10n2 = 0 + 8n + -8n -7 + -8n + 10n2 = 8n + -8n Combine like terms: 8n + -8n = 0 -7 + -8n + 10n2 = 0 Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. -0.7 + -0.8n + n2 = 0 Move the constant term to the right: Add '0.7' to each side of the equation. -0.7 + -0.8n + 0.7 + n2 = 0 + 0.7 Reorder the terms: -0.7 + 0.7 + -0.8n + n2 = 0 + 0.7 Combine like terms: -0.7 + 0.7 = 0.0 0.0 + -0.8n + n2 = 0 + 0.7 -0.8n + n2 = 0 + 0.7 Combine like terms: 0 + 0.7 = 0.7 -0.8n + n2 = 0.7 The n term is -0.8n. Take half its coefficient (-0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. -0.8n + 0.16 + n2 = 0.7 + 0.16 Reorder the terms: 0.16 + -0.8n + n2 = 0.7 + 0.16 Combine like terms: 0.7 + 0.16 = 0.86 0.16 + -0.8n + n2 = 0.86 Factor a perfect square on the left side: (n + -0.4)(n + -0.4) = 0.86 Calculate the square root of the right side: 0.92736185 Break this problem into two subproblems by setting (n + -0.4) equal to 0.92736185 and -0.92736185.Subproblem 1
n + -0.4 = 0.92736185 Simplifying n + -0.4 = 0.92736185 Reorder the terms: -0.4 + n = 0.92736185 Solving -0.4 + n = 0.92736185 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.4' to each side of the equation. -0.4 + 0.4 + n = 0.92736185 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + n = 0.92736185 + 0.4 n = 0.92736185 + 0.4 Combine like terms: 0.92736185 + 0.4 = 1.32736185 n = 1.32736185 Simplifying n = 1.32736185Subproblem 2
n + -0.4 = -0.92736185 Simplifying n + -0.4 = -0.92736185 Reorder the terms: -0.4 + n = -0.92736185 Solving -0.4 + n = -0.92736185 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.4' to each side of the equation. -0.4 + 0.4 + n = -0.92736185 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + n = -0.92736185 + 0.4 n = -0.92736185 + 0.4 Combine like terms: -0.92736185 + 0.4 = -0.52736185 n = -0.52736185 Simplifying n = -0.52736185Solution
The solution to the problem is based on the solutions from the subproblems. n = {1.32736185, -0.52736185}
