Simplifying z2 + 4z + -126 = 0 Reorder the terms: -126 + 4z + z2 = 0 Solving -126 + 4z + z2 = 0 Solving for variable 'z'. Begin completing the square. Move the constant term to the right: Add '126' to each side of the equation. -126 + 4z + 126 + z2 = 0 + 126 Reorder the terms: -126 + 126 + 4z + z2 = 0 + 126 Combine like terms: -126 + 126 = 0 0 + 4z + z2 = 0 + 126 4z + z2 = 0 + 126 Combine like terms: 0 + 126 = 126 4z + z2 = 126 The z term is 4z. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4z + 4 + z2 = 126 + 4 Reorder the terms: 4 + 4z + z2 = 126 + 4 Combine like terms: 126 + 4 = 130 4 + 4z + z2 = 130 Factor a perfect square on the left side: (z + 2)(z + 2) = 130 Calculate the square root of the right side: 11.401754251 Break this problem into two subproblems by setting (z + 2) equal to 11.401754251 and -11.401754251.Subproblem 1
z + 2 = 11.401754251 Simplifying z + 2 = 11.401754251 Reorder the terms: 2 + z = 11.401754251 Solving 2 + z = 11.401754251 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right.
