Simplifying 8x2 + -5x + 2.5 = 0 Reorder the terms: 2.5 + -5x + 8x2 = 0 Solving 2.5 + -5x + 8x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.3125 + -0.625x + x2 = 0 Move the constant term to the right: Add '-0.3125' to each side of the equation. 0.3125 + -0.625x + -0.3125 + x2 = 0 + -0.3125 Reorder the terms: 0.3125 + -0.3125 + -0.625x + x2 = 0 + -0.3125 Combine like terms: 0.3125 + -0.3125 = 0.0000 0.0000 + -0.625x + x2 = 0 + -0.3125 -0.625x + x2 = 0 + -0.3125 Combine like terms: 0 + -0.3125 = -0.3125 -0.625x + x2 = -0.3125 The x term is -0.625x. Take half its coefficient (-0.3125). Square it (0.09765625) and add it to both sides. Add '0.09765625' to each side of the equation. -0.625x + 0.09765625 + x2 = -0.3125 + 0.09765625 Reorder the terms: 0.09765625 + -0.625x + x2 = -0.3125 + 0.09765625 Combine like terms: -0.3125 + 0.09765625 = -0.21484375 0.09765625 + -0.625x + x2 = -0.21484375 Factor a perfect square on the left side: (x + -0.3125)(x + -0.3125) = -0.21484375 Can't calculate square root of the right side. The solution to this equation could not be determined.
