Simplifying 8n2 + 1 = 4n Reorder the terms: 1 + 8n2 = 4n Solving 1 + 8n2 = 4n Solving for variable 'n'. Reorder the terms: 1 + -4n + 8n2 = 4n + -4n Combine like terms: 4n + -4n = 0 1 + -4n + 8n2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.125 + -0.5n + n2 = 0 Move the constant term to the right: Add '-0.125' to each side of the equation. 0.125 + -0.5n + -0.125 + n2 = 0 + -0.125 Reorder the terms: 0.125 + -0.125 + -0.5n + n2 = 0 + -0.125 Combine like terms: 0.125 + -0.125 = 0.000 0.000 + -0.5n + n2 = 0 + -0.125 -0.5n + n2 = 0 + -0.125 Combine like terms: 0 + -0.125 = -0.125 -0.5n + n2 = -0.125 The n term is -0.5n. 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. -0.5n + 0.0625 + n2 = -0.125 + 0.0625 Reorder the terms: 0.0625 + -0.5n + n2 = -0.125 + 0.0625 Combine like terms: -0.125 + 0.0625 = -0.0625 0.0625 + -0.5n + n2 = -0.0625 Factor a perfect square on the left side: (n + -0.25)(n + -0.25) = -0.0625 Can't calculate square root of the right side. The solution to this equation could not be determined.
