Simplifying -4x2 + 5x + -5 = 0 Reorder the terms: -5 + 5x + -4x2 = 0 Solving -5 + 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'. 1.25 + -1.25x + x2 = 0 Move the constant term to the right: Add '-1.25' to each side of the equation. 1.25 + -1.25x + -1.25 + x2 = 0 + -1.25 Reorder the terms: 1.25 + -1.25 + -1.25x + x2 = 0 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + -1.25x + x2 = 0 + -1.25 -1.25x + x2 = 0 + -1.25 Combine like terms: 0 + -1.25 = -1.25 -1.25x + x2 = -1.25 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 = -1.25 + 0.390625 Reorder the terms: 0.390625 + -1.25x + x2 = -1.25 + 0.390625 Combine like terms: -1.25 + 0.390625 = -0.859375 0.390625 + -1.25x + x2 = -0.859375 Factor a perfect square on the left side: (x + -0.625)(x + -0.625) = -0.859375 Can't calculate square root of the right side. The solution to this equation could not be determined.
