Simplifying z2 + 11z = 18 Reorder the terms: 11z + z2 = 18 Solving 11z + z2 = 18 Solving for variable 'z'. Reorder the terms: -18 + 11z + z2 = 18 + -18 Combine like terms: 18 + -18 = 0 -18 + 11z + z2 = 0 Begin completing the square. Move the constant term to the right: Add '18' to each side of the equation. -18 + 11z + 18 + z2 = 0 + 18 Reorder the terms: -18 + 18 + 11z + z2 = 0 + 18 Combine like terms: -18 + 18 = 0 0 + 11z + z2 = 0 + 18 11z + z2 = 0 + 18 Combine like terms: 0 + 18 = 18 11z + z2 = 18 The z term is 11z. Take half its coefficient (5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. 11z + 30.25 + z2 = 18 + 30.25 Reorder the terms: 30.25 + 11z + z2 = 18 + 30.25 Combine like terms: 18 + 30.25 = 48.25 30.25 + 11z + z2 = 48.25 Factor a perfect square on the left side: (z + 5.5)(z + 5.5) = 48.25 Calculate the square root of the right side: 6.946221995 Break this problem into two subproblems by setting (z + 5.5) equal to 6.946221995 and -6.946221995.Subproblem 1
z + 5.5 = 6.946221995 Simplifying z + 5.5 = 6.946221995 Reorder the terms: 5.5 + z = 6.946221995 Solving 5.5 + z = 6.946221995 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '-5.5' to each side of the equation. 5.5 + -5.5 + z = 6.946221995 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + z = 6.946221995 + -5.5 z = 6.946221995 + -5.5 Combine like terms: 6.946221995 + -5.5 = 1.446221995 z = 1.446221995 Simplifying z = 1.446221995Subproblem 2
z + 5.5 = -6.946221995 Simplifying z + 5.5 = -6.946221995 Reorder the terms: 5.5 + z = -6.946221995 Solving 5.5 + z = -6.946221995 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '-5.5' to each side of the equation. 5.5 + -5.5 + z = -6.946221995 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + z = -6.946221995 + -5.5 z = -6.946221995 + -5.5 Combine like terms: -6.946221995 + -5.5 = -12.446221995 z = -12.446221995 Simplifying z = -12.446221995Solution
The solution to the problem is based on the solutions from the subproblems. z = {1.446221995, -12.446221995}
