Simplifying x2 + 0.013x + 0.0026 = 0 Reorder the terms: 0.0026 + 0.013x + x2 = 0 Solving 0.0026 + 0.013x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-0.0026' to each side of the equation. 0.0026 + 0.013x + -0.0026 + x2 = 0 + -0.0026 Reorder the terms: 0.0026 + -0.0026 + 0.013x + x2 = 0 + -0.0026 Combine like terms: 0.0026 + -0.0026 = 0.0000 0.0000 + 0.013x + x2 = 0 + -0.0026 0.013x + x2 = 0 + -0.0026 Combine like terms: 0 + -0.0026 = -0.0026 0.013x + x2 = -0.0026 The x term is 0.013x. Take half its coefficient (0.0065). Square it (0.00004225) and add it to both sides. Add '0.00004225' to each side of the equation. 0.013x + 0.00004225 + x2 = -0.0026 + 0.00004225 Reorder the terms: 0.00004225 + 0.013x + x2 = -0.0026 + 0.00004225 Combine like terms: -0.0026 + 0.00004225 = -0.00255775 0.00004225 + 0.013x + x2 = -0.00255775 Factor a perfect square on the left side: (x + 0.0065)(x + 0.0065) = -0.00255775 Can't calculate square root of the right side. The solution to this equation could not be determined.
