Simplifying z2 + -14z + -13 = 0 Reorder the terms: -13 + -14z + z2 = 0 Solving -13 + -14z + z2 = 0 Solving for variable 'z'. Begin completing the square. Move the constant term to the right: Add '13' to each side of the equation. -13 + -14z + 13 + z2 = 0 + 13 Reorder the terms: -13 + 13 + -14z + z2 = 0 + 13 Combine like terms: -13 + 13 = 0 0 + -14z + z2 = 0 + 13 -14z + z2 = 0 + 13 Combine like terms: 0 + 13 = 13 -14z + z2 = 13 The z term is -14z. Take half its coefficient (-7). Square it (49) and add it to both sides. Add '49' to each side of the equation. -14z + 49 + z2 = 13 + 49 Reorder the terms: 49 + -14z + z2 = 13 + 49 Combine like terms: 13 + 49 = 62 49 + -14z + z2 = 62 Factor a perfect square on the left side: (z + -7)(z + -7) = 62 Calculate the square root of the right side: 7.874007874 Break this problem into two subproblems by setting (z + -7) equal to 7.874007874 and -7.874007874.Subproblem 1
z + -7 = 7.874007874 Simplifying z + -7 = 7.874007874 Reorder the terms: -7 + z = 7.874007874 Solving -7 + z = 7.874007874 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + z = 7.874007874 + 7 Combine like terms: -7 + 7 = 0 0 + z = 7.874007874 + 7 z = 7.874007874 + 7 Combine like terms: 7.874007874 + 7 = 14.874007874 z = 14.874007874 Simplifying z = 14.874007874Subproblem 2
z + -7 = -7.874007874 Simplifying z + -7 = -7.874007874 Reorder the terms: -7 + z = -7.874007874 Solving -7 + z = -7.874007874 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + z = -7.874007874 + 7 Combine like terms: -7 + 7 = 0 0 + z = -7.874007874 + 7 z = -7.874007874 + 7 Combine like terms: -7.874007874 + 7 = -0.874007874 z = -0.874007874 Simplifying z = -0.874007874Solution
The solution to the problem is based on the solutions from the subproblems. z = {14.874007874, -0.874007874}
