Simplifying 32z2 + 16z + 8 = 0 Reorder the terms: 8 + 16z + 32z2 = 0 Solving 8 + 16z + 32z2 = 0 Solving for variable 'z'. Factor out the Greatest Common Factor (GCF), '8'. 8(1 + 2z + 4z2) = 0 Ignore the factor 8.Subproblem 1
Set the factor '(1 + 2z + 4z2)' equal to zero and attempt to solve: Simplifying 1 + 2z + 4z2 = 0 Solving 1 + 2z + 4z2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 0.25 + 0.5z + z2 = 0 Move the constant term to the right: Add '-0.25' to each side of the equation. 0.25 + 0.5z + -0.25 + z2 = 0 + -0.25 Reorder the terms: 0.25 + -0.25 + 0.5z + z2 = 0 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + 0.5z + z2 = 0 + -0.25 0.5z + z2 = 0 + -0.25 Combine like terms: 0 + -0.25 = -0.25 0.5z + z2 = -0.25 The z term is 0.5z. Take half its coefficient (0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. 0.5z + 0.0625 + z2 = -0.25 + 0.0625 Reorder the terms: 0.0625 + 0.5z + z2 = -0.25 + 0.0625 Combine like terms: -0.25 + 0.0625 = -0.1875 0.0625 + 0.5z + z2 = -0.1875 Factor a perfect square on the left side: (z + 0.25)(z + 0.25) = -0.1875 Can't calculate square root of the right side.
