Simplifying z2 + 7z = 4 Reorder the terms: 7z + z2 = 4 Solving 7z + z2 = 4 Solving for variable 'z'. Reorder the terms: -4 + 7z + z2 = 4 + -4 Combine like terms: 4 + -4 = 0 -4 + 7z + z2 = 0 Begin completing the square. Move the constant term to the right: Add '4' to each side of the equation. -4 + 7z + 4 + z2 = 0 + 4 Reorder the terms: -4 + 4 + 7z + z2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + 7z + z2 = 0 + 4 7z + z2 = 0 + 4 Combine like terms: 0 + 4 = 4 7z + z2 = 4 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 = 4 + 12.25 Reorder the terms: 12.25 + 7z + z2 = 4 + 12.25 Combine like terms: 4 + 12.25 = 16.25 12.25 + 7z + z2 = 16.25 Factor a perfect square on the left side: (z + 3.5)(z + 3.5) = 16.25 Calculate the square root of the right side: 4.031128874 Break this problem into two subproblems by setting (z + 3.5) equal to 4.031128874 and -4.031128874.Subproblem 1
z + 3.5 = 4.031128874 Simplifying z + 3.5 = 4.031128874 Reorder the terms: 3.5 + z = 4.031128874 Solving 3.5 + z = 4.031128874 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 = 4.031128874 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + z = 4.031128874 + -3.5 z = 4.031128874 + -3.5 Combine like terms: 4.031128874 + -3.5 = 0.531128874 z = 0.531128874 Simplifying z = 0.531128874Subproblem 2
z + 3.5 = -4.031128874 Simplifying z + 3.5 = -4.031128874 Reorder the terms: 3.5 + z = -4.031128874 Solving 3.5 + z = -4.031128874 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 = -4.031128874 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + z = -4.031128874 + -3.5 z = -4.031128874 + -3.5 Combine like terms: -4.031128874 + -3.5 = -7.531128874 z = -7.531128874 Simplifying z = -7.531128874Solution
The solution to the problem is based on the solutions from the subproblems. z = {0.531128874, -7.531128874}
