Simplifying z2 + 7z + 2 = 0 Reorder the terms: 2 + 7z + z2 = 0 Solving 2 + 7z + z2 = 0 Solving for variable 'z'. Begin completing the square. Move the constant term to the right: Add '-2' to each side of the equation. 2 + 7z + -2 + z2 = 0 + -2 Reorder the terms: 2 + -2 + 7z + z2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 7z + z2 = 0 + -2 7z + z2 = 0 + -2 Combine like terms: 0 + -2 = -2 7z + z2 = -2 The z term is 7z. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7z + 12.25 + z2 = -2 + 12.25 Reorder the terms: 12.25 + 7z + z2 = -2 + 12.25 Combine like terms: -2 + 12.25 = 10.25 12.25 + 7z + z2 = 10.25 Factor a perfect square on the left side: (z + 3.5)(z + 3.5) = 10.25 Calculate the square root of the right side: 3.201562119 Break this problem into two subproblems by setting (z + 3.5) equal to 3.201562119 and -3.201562119.Subproblem 1
z + 3.5 = 3.201562119 Simplifying z + 3.5 = 3.201562119 Reorder the terms: 3.5 + z = 3.201562119 Solving 3.5 + z = 3.201562119 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + z = 3.201562119 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + z = 3.201562119 + -3.5 z = 3.201562119 + -3.5 Combine like terms: 3.201562119 + -3.5 = -0.298437881 z = -0.298437881 Simplifying z = -0.298437881Subproblem 2
z + 3.5 = -3.201562119 Simplifying z + 3.5 = -3.201562119 Reorder the terms: 3.5 + z = -3.201562119 Solving 3.5 + z = -3.201562119 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + z = -3.201562119 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + z = -3.201562119 + -3.5 z = -3.201562119 + -3.5 Combine like terms: -3.201562119 + -3.5 = -6.701562119 z = -6.701562119 Simplifying z = -6.701562119Solution
The solution to the problem is based on the solutions from the subproblems. z = {-0.298437881, -6.701562119}
