Simplifying 7 + 7z + z2 = 0 Solving 7 + 7z + z2 = 0 Solving for variable 'z'. Begin completing the square. Move the constant term to the right: Add '-7' to each side of the equation. 7 + 7z + -7 + z2 = 0 + -7 Reorder the terms: 7 + -7 + 7z + z2 = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 7z + z2 = 0 + -7 7z + z2 = 0 + -7 Combine like terms: 0 + -7 = -7 7z + z2 = -7 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 = -7 + 12.25 Reorder the terms: 12.25 + 7z + z2 = -7 + 12.25 Combine like terms: -7 + 12.25 = 5.25 12.25 + 7z + z2 = 5.25 Factor a perfect square on the left side: (z + 3.5)(z + 3.5) = 5.25 Calculate the square root of the right side: 2.291287847 Break this problem into two subproblems by setting (z + 3.5) equal to 2.291287847 and -2.291287847.Subproblem 1
z + 3.5 = 2.291287847 Simplifying z + 3.5 = 2.291287847 Reorder the terms: 3.5 + z = 2.291287847 Solving 3.5 + z = 2.291287847 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 = 2.291287847 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + z = 2.291287847 + -3.5 z = 2.291287847 + -3.5 Combine like terms: 2.291287847 + -3.5 = -1.208712153 z = -1.208712153 Simplifying z = -1.208712153Subproblem 2
z + 3.5 = -2.291287847 Simplifying z + 3.5 = -2.291287847 Reorder the terms: 3.5 + z = -2.291287847 Solving 3.5 + z = -2.291287847 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 = -2.291287847 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + z = -2.291287847 + -3.5 z = -2.291287847 + -3.5 Combine like terms: -2.291287847 + -3.5 = -5.791287847 z = -5.791287847 Simplifying z = -5.791287847Solution
The solution to the problem is based on the solutions from the subproblems. z = {-1.208712153, -5.791287847}
