Simplifying 4x2 + -5x + 13 = 0 Reorder the terms: 13 + -5x + 4x2 = 0 Solving 13 + -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'. 3.25 + -1.25x + x2 = 0 Move the constant term to the right: Add '-3.25' to each side of the equation. 3.25 + -1.25x + -3.25 + x2 = 0 + -3.25 Reorder the terms: 3.25 + -3.25 + -1.25x + x2 = 0 + -3.25 Combine like terms: 3.25 + -3.25 = 0.00 0.00 + -1.25x + x2 = 0 + -3.25 -1.25x + x2 = 0 + -3.25 Combine like terms: 0 + -3.25 = -3.25 -1.25x + x2 = -3.25 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 = -3.25 + 0.390625 Reorder the terms: 0.390625 + -1.25x + x2 = -3.25 + 0.390625 Combine like terms: -3.25 + 0.390625 = -2.859375 0.390625 + -1.25x + x2 = -2.859375 Factor a perfect square on the left side: (x + -0.625)(x + -0.625) = -2.859375 Can't calculate square root of the right side. The solution to this equation could not be determined.
