Simplifying n2 + 9n + -4000 = 0 Reorder the terms: -4000 + 9n + n2 = 0 Solving -4000 + 9n + n2 = 0 Solving for variable 'n'. Begin completing the square. Move the constant term to the right: Add '4000' to each side of the equation. -4000 + 9n + 4000 + n2 = 0 + 4000 Reorder the terms: -4000 + 4000 + 9n + n2 = 0 + 4000 Combine like terms: -4000 + 4000 = 0 0 + 9n + n2 = 0 + 4000 9n + n2 = 0 + 4000 Combine like terms: 0 + 4000 = 4000 9n + n2 = 4000 The n term is 9n. Take half its coefficient (4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. 9n + 20.25 + n2 = 4000 + 20.25 Reorder the terms: 20.25 + 9n + n2 = 4000 + 20.25 Combine like terms: 4000 + 20.25 = 4020.25 20.25 + 9n + n2 = 4020.25 Factor a perfect square on the left side: (n + 4.5)(n + 4.5) = 4020.25 Calculate the square root of the right side: 63.405441407 Break this problem into two subproblems by setting (n + 4.5) equal to 63.405441407 and -63.405441407.Subproblem 1
n + 4.5 = 63.405441407 Simplifying n + 4.5 = 63.405441407 Reorder the terms: 4.5 + n = 63.405441407 Solving 4.5 + n = 63.405441407 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + n = 63.405441407 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + n = 63.405441407 + -4.5 n = 63.405441407 + -4.5 Combine like terms: 63.405441407 + -4.5 = 58.905441407 n = 58.905441407 Simplifying n = 58.905441407Subproblem 2
n + 4.5 = -63.405441407 Simplifying n + 4.5 = -63.405441407 Reorder the terms: 4.5 + n = -63.405441407 Solving 4.5 + n = -63.405441407 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + n = -63.405441407 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + n = -63.405441407 + -4.5 n = -63.405441407 + -4.5 Combine like terms: -63.405441407 + -4.5 = -67.905441407 n = -67.905441407 Simplifying n = -67.905441407Solution
