Simplifying z2 + 12z = 146 Reorder the terms: 12z + z2 = 146 Solving 12z + z2 = 146 Solving for variable 'z'. Reorder the terms: -146 + 12z + z2 = 146 + -146 Combine like terms: 146 + -146 = 0 -146 + 12z + z2 = 0 Begin completing the square. Move the constant term to the right: Add '146' to each side of the equation. -146 + 12z + 146 + z2 = 0 + 146 Reorder the terms: -146 + 146 + 12z + z2 = 0 + 146 Combine like terms: -146 + 146 = 0 0 + 12z + z2 = 0 + 146 12z + z2 = 0 + 146 Combine like terms: 0 + 146 = 146 12z + z2 = 146 The z term is 12z. Take half its coefficient (6). Square it (36) and add it to both sides. Add '36' to each side of the equation. 12z + 36 + z2 = 146 + 36 Reorder the terms: 36 + 12z + z2 = 146 + 36 Combine like terms: 146 + 36 = 182 36 + 12z + z2 = 182 Factor a perfect square on the left side: (z + 6)(z + 6) = 182 Calculate the square root of the right side: 13.490737563 Break this problem into two subproblems by setting (z + 6) equal to 13.490737563 and -13.490737563.Subproblem 1
z + 6 = 13.490737563 Simplifying z + 6 = 13.490737563 Reorder the terms: 6 + z = 13.490737563 Solving 6 + z = 13.490737563 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right.
