Simplifying 8z + 25 = 4z2 Reorder the terms: 25 + 8z = 4z2 Solving 25 + 8z = 4z2 Solving for variable 'z'. Combine like terms: 4z2 + -4z2 = 0 25 + 8z + -4z2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -6.25 + -2z + z2 = 0 Move the constant term to the right: Add '6.25' to each side of the equation. -6.25 + -2z + 6.25 + z2 = 0 + 6.25 Reorder the terms: -6.25 + 6.25 + -2z + z2 = 0 + 6.25 Combine like terms: -6.25 + 6.25 = 0.00 0.00 + -2z + z2 = 0 + 6.25 -2z + z2 = 0 + 6.25 Combine like terms: 0 + 6.25 = 6.25 -2z + z2 = 6.25 The z term is -2z. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2z + 1 + z2 = 6.25 + 1 Reorder the terms: 1 + -2z + z2 = 6.25 + 1 Combine like terms: 6.25 + 1 = 7.25 1 + -2z + z2 = 7.25 Factor a perfect square on the left side: (z + -1)(z + -1) = 7.25 Calculate the square root of the right side: 2.692582404 Break this problem into two subproblems by setting (z + -1) equal to 2.692582404 and -2.692582404.Subproblem 1
z + -1 = 2.692582404 Simplifying z + -1 = 2.692582404 Reorder the terms: -1 + z = 2.692582404 Solving -1 + z = 2.692582404 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + z = 2.692582404 + 1 Combine like terms: -1 + 1 = 0 0 + z = 2.692582404 + 1 z = 2.692582404 + 1 Combine like terms: 2.692582404 + 1 = 3.692582404 z = 3.692582404 Simplifying z = 3.692582404Subproblem 2
z + -1 = -2.692582404 Simplifying z + -1 = -2.692582404 Reorder the terms: -1 + z = -2.692582404 Solving -1 + z = -2.692582404 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + z = -2.692582404 + 1 Combine like terms: -1 + 1 = 0 0 + z = -2.692582404 + 1 z = -2.692582404 + 1 Combine like terms: -2.692582404 + 1 = -1.692582404 z = -1.692582404 Simplifying z = -1.692582404Solution
The solution to the problem is based on the solutions from the subproblems. z = {3.692582404, -1.692582404}
