Simplifying z2 + 12z + 16 = 0 Reorder the terms: 16 + 12z + z2 = 0 Solving 16 + 12z + z2 = 0 Solving for variable 'z'. Begin completing the square. Move the constant term to the right: Add '-16' to each side of the equation. 16 + 12z + -16 + z2 = 0 + -16 Reorder the terms: 16 + -16 + 12z + z2 = 0 + -16 Combine like terms: 16 + -16 = 0 0 + 12z + z2 = 0 + -16 12z + z2 = 0 + -16 Combine like terms: 0 + -16 = -16 12z + z2 = -16 The z term is 12z. Take half its coefficient (6). Square it (36) and add it to both sides. Add '36' to each side of the equation. 12z + 36 + z2 = -16 + 36 Reorder the terms: 36 + 12z + z2 = -16 + 36 Combine like terms: -16 + 36 = 20 36 + 12z + z2 = 20 Factor a perfect square on the left side: (z + 6)(z + 6) = 20 Calculate the square root of the right side: 4.472135955 Break this problem into two subproblems by setting (z + 6) equal to 4.472135955 and -4.472135955.Subproblem 1
z + 6 = 4.472135955 Simplifying z + 6 = 4.472135955 Reorder the terms: 6 + z = 4.472135955 Solving 6 + z = 4.472135955 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + z = 4.472135955 + -6 Combine like terms: 6 + -6 = 0 0 + z = 4.472135955 + -6 z = 4.472135955 + -6 Combine like terms: 4.472135955 + -6 = -1.527864045 z = -1.527864045 Simplifying z = -1.527864045Subproblem 2
z + 6 = -4.472135955 Simplifying z + 6 = -4.472135955 Reorder the terms: 6 + z = -4.472135955 Solving 6 + z = -4.472135955 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + z = -4.472135955 + -6 Combine like terms: 6 + -6 = 0 0 + z = -4.472135955 + -6 z = -4.472135955 + -6 Combine like terms: -4.472135955 + -6 = -10.472135955 z = -10.472135955 Simplifying z = -10.472135955Solution
The solution to the problem is based on the solutions from the subproblems. z = {-1.527864045, -10.472135955}
