Simplifying 20x2 + -1x + 1 = 0 Reorder the terms: 1 + -1x + 20x2 = 0 Solving 1 + -1x + 20x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. 0.05 + -0.05x + x2 = 0 Move the constant term to the right: Add '-0.05' to each side of the equation. 0.05 + -0.05x + -0.05 + x2 = 0 + -0.05 Reorder the terms: 0.05 + -0.05 + -0.05x + x2 = 0 + -0.05 Combine like terms: 0.05 + -0.05 = 0.00 0.00 + -0.05x + x2 = 0 + -0.05 -0.05x + x2 = 0 + -0.05 Combine like terms: 0 + -0.05 = -0.05 -0.05x + x2 = -0.05 The x term is -0.05x. Take half its coefficient (-0.025). Square it (0.000625) and add it to both sides. Add '0.000625' to each side of the equation. -0.05x + 0.000625 + x2 = -0.05 + 0.000625 Reorder the terms: 0.000625 + -0.05x + x2 = -0.05 + 0.000625 Combine like terms: -0.05 + 0.000625 = -0.049375 0.000625 + -0.05x + x2 = -0.049375 Factor a perfect square on the left side: (x + -0.025)(x + -0.025) = -0.049375 Can't calculate square root of the right side. The solution to this equation could not be determined.
