Simplifying z2 + -18z = 7 Reorder the terms: -18z + z2 = 7 Solving -18z + z2 = 7 Solving for variable 'z'. Reorder the terms: -7 + -18z + z2 = 7 + -7 Combine like terms: 7 + -7 = 0 -7 + -18z + z2 = 0 Begin completing the square. Move the constant term to the right: Add '7' to each side of the equation. -7 + -18z + 7 + z2 = 0 + 7 Reorder the terms: -7 + 7 + -18z + z2 = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -18z + z2 = 0 + 7 -18z + z2 = 0 + 7 Combine like terms: 0 + 7 = 7 -18z + z2 = 7 The z term is -18z. Take half its coefficient (-9). Square it (81) and add it to both sides. Add '81' to each side of the equation. -18z + 81 + z2 = 7 + 81 Reorder the terms: 81 + -18z + z2 = 7 + 81 Combine like terms: 7 + 81 = 88 81 + -18z + z2 = 88 Factor a perfect square on the left side: (z + -9)(z + -9) = 88 Calculate the square root of the right side: 9.38083152 Break this problem into two subproblems by setting (z + -9) equal to 9.38083152 and -9.38083152.Subproblem 1
z + -9 = 9.38083152 Simplifying z + -9 = 9.38083152 Reorder the terms: -9 + z = 9.38083152 Solving -9 + z = 9.38083152 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + z = 9.38083152 + 9 Combine like terms: -9 + 9 = 0 0 + z = 9.38083152 + 9 z = 9.38083152 + 9 Combine like terms: 9.38083152 + 9 = 18.38083152 z = 18.38083152 Simplifying z = 18.38083152Subproblem 2
z + -9 = -9.38083152 Simplifying z + -9 = -9.38083152 Reorder the terms: -9 + z = -9.38083152 Solving -9 + z = -9.38083152 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + z = -9.38083152 + 9 Combine like terms: -9 + 9 = 0 0 + z = -9.38083152 + 9 z = -9.38083152 + 9 Combine like terms: -9.38083152 + 9 = -0.38083152 z = -0.38083152 Simplifying z = -0.38083152Solution
The solution to the problem is based on the solutions from the subproblems. z = {18.38083152, -0.38083152}
