Simplifying 8n2 + 6n + 2 = 0 Reorder the terms: 2 + 6n + 8n2 = 0 Solving 2 + 6n + 8n2 = 0 Solving for variable 'n'. Factor out the Greatest Common Factor (GCF), '2'. 2(1 + 3n + 4n2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(1 + 3n + 4n2)' equal to zero and attempt to solve: Simplifying 1 + 3n + 4n2 = 0 Solving 1 + 3n + 4n2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 0.25 + 0.75n + n2 = 0 Move the constant term to the right: Add '-0.25' to each side of the equation. 0.25 + 0.75n + -0.25 + n2 = 0 + -0.25 Reorder the terms: 0.25 + -0.25 + 0.75n + n2 = 0 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + 0.75n + n2 = 0 + -0.25 0.75n + n2 = 0 + -0.25 Combine like terms: 0 + -0.25 = -0.25 0.75n + n2 = -0.25 The n term is 0.75n. Take half its coefficient (0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. 0.75n + 0.140625 + n2 = -0.25 + 0.140625 Reorder the terms: 0.140625 + 0.75n + n2 = -0.25 + 0.140625 Combine like terms: -0.25 + 0.140625 = -0.109375 0.140625 + 0.75n + n2 = -0.109375 Factor a perfect square on the left side: (n + 0.375)(n + 0.375) = -0.109375 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
