Simplifying -1x2 + -0.000018x + -0.0000045 = 0 Reorder the terms: -0.0000045 + -0.000018x + -1x2 = 0 Solving -0.0000045 + -0.000018x + -1x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 0.0000045 + 0.000018x + x2 = 0 Move the constant term to the right: Add '-0.0000045' to each side of the equation. 0.0000045 + 0.000018x + -0.0000045 + x2 = 0 + -0.0000045 Reorder the terms: 0.0000045 + -0.0000045 + 0.000018x + x2 = 0 + -0.0000045 Combine like terms: 0.0000045 + -0.0000045 = 0.0000000 0.0000000 + 0.000018x + x2 = 0 + -0.0000045 0.000018x + x2 = 0 + -0.0000045 Combine like terms: 0 + -0.0000045 = -0.0000045 0.000018x + x2 = -0.0000045 The x term is 0.000018x. Take half its coefficient (0.000009). Square it (0.000000000081) and add it to both sides. Add '0.000000000081' to each side of the equation. 0.000018x + 0.000000000081 + x2 = -0.0000045 + 0.000000000081 Reorder the terms: 0.000000000081 + 0.000018x + x2 = -0.0000045 + 0.000000000081 Combine like terms: -0.0000045 + 0.000000000081 = -0.000004499919 0.000000000081 + 0.000018x + x2 = -0.000004499919 Factor a perfect square on the left side: (x + 0.000009)(x + 0.000009) = -0.000004499919 Can't calculate square root of the right side. The solution to this equation could not be determined.
