Simplifying (4x4) + -1(x2) + 4 = 0 Reorder the terms: 4 + -1x2 + (4x4) = 0 Solving 4 + -1x2 + (4x4) = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 1 + -0.25x2 + x4 = 0 Move the constant term to the right: Add '-1' to each side of the equation. 1 + -0.25x2 + -1 + x4 = 0 + -1 Reorder the terms: 1 + -1 + -0.25x2 + x4 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -0.25x2 + x4 = 0 + -1 -0.25x2 + x4 = 0 + -1 Combine like terms: 0 + -1 = -1 -0.25x2 + x4 = -1 The x term is -0.25x2. 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. -0.25x2 + 0.015625 + x4 = -1 + 0.015625 Reorder the terms: 0.015625 + -0.25x2 + x4 = -1 + 0.015625 Combine like terms: -1 + 0.015625 = -0.984375 0.015625 + -0.25x2 + x4 = -0.984375 Factor a perfect square on the left side: ((x2) + -0.125)((x2) + -0.125) = -0.984375 Can't calculate square root of the right side. The solution to this equation could not be determined.
