Simplifying 2(z + 4) * z = 5 Reorder the terms: 2(4 + z) * z = 5 Reorder the terms for easier multiplication: 2z(4 + z) = 5 (4 * 2z + z * 2z) = 5 (8z + 2z2) = 5 Solving 8z + 2z2 = 5 Solving for variable 'z'. Reorder the terms: -5 + 8z + 2z2 = 5 + -5 Combine like terms: 5 + -5 = 0 -5 + 8z + 2z2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -2.5 + 4z + z2 = 0 Move the constant term to the right: Add '2.5' to each side of the equation. -2.5 + 4z + 2.5 + z2 = 0 + 2.5 Reorder the terms: -2.5 + 2.5 + 4z + z2 = 0 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + 4z + z2 = 0 + 2.5 4z + z2 = 0 + 2.5 Combine like terms: 0 + 2.5 = 2.5 4z + z2 = 2.5 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 = 2.5 + 4 Reorder the terms: 4 + 4z + z2 = 2.5 + 4 Combine like terms: 2.5 + 4 = 6.5 4 + 4z + z2 = 6.5 Factor a perfect square on the left side: (z + 2)(z + 2) = 6.5 Calculate the square root of the right side: 2.549509757 Break this problem into two subproblems by setting (z + 2) equal to 2.549509757 and -2.549509757.Subproblem 1
z + 2 = 2.549509757 Simplifying z + 2 = 2.549509757 Reorder the terms: 2 + z = 2.549509757 Solving 2 + z = 2.549509757 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + z = 2.549509757 + -2 Combine like terms: 2 + -2 = 0 0 + z = 2.549509757 + -2 z = 2.549509757 + -2 Combine like terms: 2.549509757 + -2 = 0.549509757 z = 0.549509757 Simplifying z = 0.549509757Subproblem 2
z + 2 = -2.549509757 Simplifying z + 2 = -2.549509757 Reorder the terms: 2 + z = -2.549509757 Solving 2 + z = -2.549509757 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + z = -2.549509757 + -2 Combine like terms: 2 + -2 = 0 0 + z = -2.549509757 + -2 z = -2.549509757 + -2 Combine like terms: -2.549509757 + -2 = -4.549509757 z = -4.549509757 Simplifying z = -4.549509757Solution
