Simplifying -0.25x + x2 = -0.1875 Solving -0.25x + x2 = -0.1875 Solving for variable 'x'. Reorder the terms: 0.1875 + -0.25x + x2 = -0.1875 + 0.1875 Combine like terms: -0.1875 + 0.1875 = 0.0000 0.1875 + -0.25x + x2 = 0.0000 Begin completing the square. Move the constant term to the right: Add '-0.1875' to each side of the equation. 0.1875 + -0.25x + -0.1875 + x2 = 0.0000 + -0.1875 Reorder the terms: 0.1875 + -0.1875 + -0.25x + x2 = 0.0000 + -0.1875 Combine like terms: 0.1875 + -0.1875 = 0.0000 0.0000 + -0.25x + x2 = 0.0000 + -0.1875 -0.25x + x2 = 0.0000 + -0.1875 Combine like terms: 0.0000 + -0.1875 = -0.1875 -0.25x + x2 = -0.1875 The x term is -0.25x. Take half its coefficient (-0.125). Square it (0.015625) and add it to both sides. Add '0.015625' to each side of the equation. -0.25x + 0.015625 + x2 = -0.1875 + 0.015625 Reorder the terms: 0.015625 + -0.25x + x2 = -0.1875 + 0.015625 Combine like terms: -0.1875 + 0.015625 = -0.171875 0.015625 + -0.25x + x2 = -0.171875 Factor a perfect square on the left side: (x + -0.125)(x + -0.125) = -0.171875 Can't calculate square root of the right side. The solution to this equation could not be determined.
