Simplifying z2 + -1.72z + 0.72 = 0 Reorder the terms: 0.72 + -1.72z + z2 = 0 Solving 0.72 + -1.72z + z2 = 0 Solving for variable 'z'. Begin completing the square. Move the constant term to the right: Add '-0.72' to each side of the equation. 0.72 + -1.72z + -0.72 + z2 = 0 + -0.72 Reorder the terms: 0.72 + -0.72 + -1.72z + z2 = 0 + -0.72 Combine like terms: 0.72 + -0.72 = 0.00 0.00 + -1.72z + z2 = 0 + -0.72 -1.72z + z2 = 0 + -0.72 Combine like terms: 0 + -0.72 = -0.72 -1.72z + z2 = -0.72 The z term is -1.72z. Take half its coefficient (-0.86). Square it (0.7396) and add it to both sides. Add '0.7396' to each side of the equation. -1.72z + 0.7396 + z2 = -0.72 + 0.7396 Reorder the terms: 0.7396 + -1.72z + z2 = -0.72 + 0.7396 Combine like terms: -0.72 + 0.7396 = 0.0196 0.7396 + -1.72z + z2 = 0.0196 Factor a perfect square on the left side: (z + -0.86)(z + -0.86) = 0.0196 Calculate the square root of the right side: 0.14 Break this problem into two subproblems by setting (z + -0.86) equal to 0.14 and -0.14.Subproblem 1
z + -0.86 = 0.14 Simplifying z + -0.86 = 0.14 Reorder the terms: -0.86 + z = 0.14 Solving -0.86 + z = 0.14 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '0.86' to each side of the equation. -0.86 + 0.86 + z = 0.14 + 0.86 Combine like terms: -0.86 + 0.86 = 0.00 0.00 + z = 0.14 + 0.86 z = 0.14 + 0.86 Combine like terms: 0.14 + 0.86 = 1 z = 1 Simplifying z = 1Subproblem 2
z + -0.86 = -0.14 Simplifying z + -0.86 = -0.14 Reorder the terms: -0.86 + z = -0.14 Solving -0.86 + z = -0.14 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '0.86' to each side of the equation. -0.86 + 0.86 + z = -0.14 + 0.86 Combine like terms: -0.86 + 0.86 = 0.00 0.00 + z = -0.14 + 0.86 z = -0.14 + 0.86 Combine like terms: -0.14 + 0.86 = 0.72 z = 0.72 Simplifying z = 0.72Solution
The solution to the problem is based on the solutions from the subproblems. z = {1, 0.72}
