Simplifying 4x2 + -1x + 21 = 0 Reorder the terms: 21 + -1x + 4x2 = 0 Solving 21 + -1x + 4x2 = 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'. 5.25 + -0.25x + x2 = 0 Move the constant term to the right: Add '-5.25' to each side of the equation. 5.25 + -0.25x + -5.25 + x2 = 0 + -5.25 Reorder the terms: 5.25 + -5.25 + -0.25x + x2 = 0 + -5.25 Combine like terms: 5.25 + -5.25 = 0.00 0.00 + -0.25x + x2 = 0 + -5.25 -0.25x + x2 = 0 + -5.25 Combine like terms: 0 + -5.25 = -5.25 -0.25x + x2 = -5.25 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 = -5.25 + 0.015625 Reorder the terms: 0.015625 + -0.25x + x2 = -5.25 + 0.015625 Combine like terms: -5.25 + 0.015625 = -5.234375 0.015625 + -0.25x + x2 = -5.234375 Factor a perfect square on the left side: (x + -0.125)(x + -0.125) = -5.234375 Can't calculate square root of the right side. The solution to this equation could not be determined.
