Begin completing the square. Divide all terms by 7 the coefficient of the squared term: Divide each side by '7'. 0.2857142857 + -1x + x2 = 0 Move the constant term to the right: Add '-0.2857142857' to each side of the equation. 0.2857142857 + -1x + -0.2857142857 + x2 = 0 + -0.2857142857 Reorder the terms: 0.2857142857 + -0.2857142857 + -1x + x2 = 0 + -0.2857142857 Combine like terms: 0.2857142857 + -0.2857142857 = 0.0000000000 0.0000000000 + -1x + x2 = 0 + -0.2857142857 -1x + x2 = 0 + -0.2857142857 Combine like terms: 0 + -0.2857142857 = -0.2857142857 -1x + x2 = -0.2857142857 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = -0.2857142857 + 0.25 Reorder the terms: 0.25 + -1x + x2 = -0.2857142857 + 0.25 Combine like terms: -0.2857142857 + 0.25 = -0.0357142857 0.25 + -1x + x2 = -0.0357142857 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = -0.0357142857 Can't calculate square root of the right side. The solution to this equation could not be determined.
