Simplifying z2 + -14 = z + 7 Reorder the terms: -14 + z2 = z + 7 Reorder the terms: -14 + z2 = 7 + z Solving -14 + z2 = 7 + z Solving for variable 'z'. Reorder the terms: -14 + -7 + -1z + z2 = 7 + z + -7 + -1z Combine like terms: -14 + -7 = -21 -21 + -1z + z2 = 7 + z + -7 + -1z Reorder the terms: -21 + -1z + z2 = 7 + -7 + z + -1z Combine like terms: 7 + -7 = 0 -21 + -1z + z2 = 0 + z + -1z -21 + -1z + z2 = z + -1z Combine like terms: z + -1z = 0 -21 + -1z + z2 = 0 Begin completing the square. Move the constant term to the right: Add '21' to each side of the equation. -21 + -1z + 21 + z2 = 0 + 21 Reorder the terms: -21 + 21 + -1z + z2 = 0 + 21 Combine like terms: -21 + 21 = 0 0 + -1z + z2 = 0 + 21 -1z + z2 = 0 + 21 Combine like terms: 0 + 21 = 21 -1z + z2 = 21 The z term is -1z. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1z + 0.25 + z2 = 21 + 0.25 Reorder the terms: 0.25 + -1z + z2 = 21 + 0.25 Combine like terms: 21 + 0.25 = 21.25 0.25 + -1z + z2 = 21.25 Factor a perfect square on the left side: (z + -0.5)(z + -0.5) = 21.25 Calculate the square root of the right side: 4.609772229 Break this problem into two subproblems by setting (z + -0.5) equal to 4.609772229 and -4.609772229.Subproblem 1
z + -0.5 = 4.609772229 Simplifying z + -0.5 = 4.609772229 Reorder the terms: -0.5 + z = 4.609772229 Solving -0.5 + z = 4.609772229 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + z = 4.609772229 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + z = 4.609772229 + 0.5 z = 4.609772229 + 0.5 Combine like terms: 4.609772229 + 0.5 = 5.109772229 z = 5.109772229 Simplifying z = 5.109772229Subproblem 2
z + -0.5 = -4.609772229 Simplifying z + -0.5 = -4.609772229 Reorder the terms: -0.5 + z = -4.609772229 Solving -0.5 + z = -4.609772229 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + z = -4.609772229 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + z = -4.609772229 + 0.5 z = -4.609772229 + 0.5 Combine like terms: -4.609772229 + 0.5 = -4.109772229 z = -4.109772229 Simplifying z = -4.109772229Solution
The solution to the problem is based on the solutions from the subproblems. z = {5.109772229, -4.109772229}
