Simplifying n2 + 6n + -12 = 0 Reorder the terms: -12 + 6n + n2 = 0 Solving -12 + 6n + n2 = 0 Solving for variable 'n'. Begin completing the square. Move the constant term to the right: Add '12' to each side of the equation. -12 + 6n + 12 + n2 = 0 + 12 Reorder the terms: -12 + 12 + 6n + n2 = 0 + 12 Combine like terms: -12 + 12 = 0 0 + 6n + n2 = 0 + 12 6n + n2 = 0 + 12 Combine like terms: 0 + 12 = 12 6n + n2 = 12 The n term is 6n. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6n + 9 + n2 = 12 + 9 Reorder the terms: 9 + 6n + n2 = 12 + 9 Combine like terms: 12 + 9 = 21 9 + 6n + n2 = 21 Factor a perfect square on the left side: (n + 3)(n + 3) = 21 Calculate the square root of the right side: 4.582575695 Break this problem into two subproblems by setting (n + 3) equal to 4.582575695 and -4.582575695.Subproblem 1
n + 3 = 4.582575695 Simplifying n + 3 = 4.582575695 Reorder the terms: 3 + n = 4.582575695 Solving 3 + n = 4.582575695 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + n = 4.582575695 + -3 Combine like terms: 3 + -3 = 0 0 + n = 4.582575695 + -3 n = 4.582575695 + -3 Combine like terms: 4.582575695 + -3 = 1.582575695 n = 1.582575695 Simplifying n = 1.582575695Subproblem 2
n + 3 = -4.582575695 Simplifying n + 3 = -4.582575695 Reorder the terms: 3 + n = -4.582575695 Solving 3 + n = -4.582575695 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + n = -4.582575695 + -3 Combine like terms: 3 + -3 = 0 0 + n = -4.582575695 + -3 n = -4.582575695 + -3 Combine like terms: -4.582575695 + -3 = -7.582575695 n = -7.582575695 Simplifying n = -7.582575695Solution
