Simplifying 25z2 + -30z + -9 = 0 Reorder the terms: -9 + -30z + 25z2 = 0 Solving -9 + -30z + 25z2 = 0 Solving for variable 'z'. Begin completing the square. Divide all terms by 25 the coefficient of the squared term: Divide each side by '25'. -0.36 + -1.2z + z2 = 0 Move the constant term to the right: Add '0.36' to each side of the equation. -0.36 + -1.2z + 0.36 + z2 = 0 + 0.36 Reorder the terms: -0.36 + 0.36 + -1.2z + z2 = 0 + 0.36 Combine like terms: -0.36 + 0.36 = 0.00 0.00 + -1.2z + z2 = 0 + 0.36 -1.2z + z2 = 0 + 0.36 Combine like terms: 0 + 0.36 = 0.36 -1.2z + z2 = 0.36 The z term is -1.2z. Take half its coefficient (-0.6). Square it (0.36) and add it to both sides. Add '0.36' to each side of the equation. -1.2z + 0.36 + z2 = 0.36 + 0.36 Reorder the terms: 0.36 + -1.2z + z2 = 0.36 + 0.36 Combine like terms: 0.36 + 0.36 = 0.72 0.36 + -1.2z + z2 = 0.72 Factor a perfect square on the left side: (z + -0.6)(z + -0.6) = 0.72 Calculate the square root of the right side: 0.848528137 Break this problem into two subproblems by setting (z + -0.6) equal to 0.848528137 and -0.848528137.Subproblem 1
z + -0.6 = 0.848528137 Simplifying z + -0.6 = 0.848528137 Reorder the terms: -0.6 + z = 0.848528137 Solving -0.6 + z = 0.848528137 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '0.6' to each side of the equation. -0.6 + 0.6 + z = 0.848528137 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + z = 0.848528137 + 0.6 z = 0.848528137 + 0.6 Combine like terms: 0.848528137 + 0.6 = 1.448528137 z = 1.448528137 Simplifying z = 1.448528137Subproblem 2
z + -0.6 = -0.848528137 Simplifying z + -0.6 = -0.848528137 Reorder the terms: -0.6 + z = -0.848528137 Solving -0.6 + z = -0.848528137 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '0.6' to each side of the equation. -0.6 + 0.6 + z = -0.848528137 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + z = -0.848528137 + 0.6 z = -0.848528137 + 0.6 Combine like terms: -0.848528137 + 0.6 = -0.248528137 z = -0.248528137 Simplifying z = -0.248528137Solution
