Simplifying 4x2 + 5x + 127 = 0 Reorder the terms: 127 + 5x + 4x2 = 0 Solving 127 + 5x + 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'. 31.75 + 1.25x + x2 = 0 Move the constant term to the right: Add '-31.75' to each side of the equation. 31.75 + 1.25x + -31.75 + x2 = 0 + -31.75 Reorder the terms: 31.75 + -31.75 + 1.25x + x2 = 0 + -31.75 Combine like terms: 31.75 + -31.75 = 0.00 0.00 + 1.25x + x2 = 0 + -31.75 1.25x + x2 = 0 + -31.75 Combine like terms: 0 + -31.75 = -31.75 1.25x + x2 = -31.75 The x term is 1.25x. Take half its coefficient (0.625). Square it (0.390625) and add it to both sides. Add '0.390625' to each side of the equation. 1.25x + 0.390625 + x2 = -31.75 + 0.390625 Reorder the terms: 0.390625 + 1.25x + x2 = -31.75 + 0.390625 Combine like terms: -31.75 + 0.390625 = -31.359375 0.390625 + 1.25x + x2 = -31.359375 Factor a perfect square on the left side: (x + 0.625)(x + 0.625) = -31.359375 Can't calculate square root of the right side. The solution to this equation could not be determined.
