Simplifying n2 + 8n + -40 = 9 Reorder the terms: -40 + 8n + n2 = 9 Solving -40 + 8n + n2 = 9 Solving for variable 'n'. Reorder the terms: -40 + -9 + 8n + n2 = 9 + -9 Combine like terms: -40 + -9 = -49 -49 + 8n + n2 = 9 + -9 Combine like terms: 9 + -9 = 0 -49 + 8n + n2 = 0 Begin completing the square. Move the constant term to the right: Add '49' to each side of the equation. -49 + 8n + 49 + n2 = 0 + 49 Reorder the terms: -49 + 49 + 8n + n2 = 0 + 49 Combine like terms: -49 + 49 = 0 0 + 8n + n2 = 0 + 49 8n + n2 = 0 + 49 Combine like terms: 0 + 49 = 49 8n + n2 = 49 The n term is 8n. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8n + 16 + n2 = 49 + 16 Reorder the terms: 16 + 8n + n2 = 49 + 16 Combine like terms: 49 + 16 = 65 16 + 8n + n2 = 65 Factor a perfect square on the left side: (n + 4)(n + 4) = 65 Calculate the square root of the right side: 8.062257748 Break this problem into two subproblems by setting (n + 4) equal to 8.062257748 and -8.062257748.Subproblem 1
n + 4 = 8.062257748 Simplifying n + 4 = 8.062257748 Reorder the terms: 4 + n = 8.062257748 Solving 4 + n = 8.062257748 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + n = 8.062257748 + -4 Combine like terms: 4 + -4 = 0 0 + n = 8.062257748 + -4 n = 8.062257748 + -4 Combine like terms: 8.062257748 + -4 = 4.062257748 n = 4.062257748 Simplifying n = 4.062257748Subproblem 2
n + 4 = -8.062257748 Simplifying n + 4 = -8.062257748 Reorder the terms: 4 + n = -8.062257748 Solving 4 + n = -8.062257748 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + n = -8.062257748 + -4 Combine like terms: 4 + -4 = 0 0 + n = -8.062257748 + -4 n = -8.062257748 + -4 Combine like terms: -8.062257748 + -4 = -12.062257748 n = -12.062257748 Simplifying n = -12.062257748Solution
