Simplifying 8x2 + -4x + 525 = 0 Reorder the terms: 525 + -4x + 8x2 = 0 Solving 525 + -4x + 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'. 65.625 + -0.5x + x2 = 0 Move the constant term to the right: Add '-65.625' to each side of the equation. 65.625 + -0.5x + -65.625 + x2 = 0 + -65.625 Reorder the terms: 65.625 + -65.625 + -0.5x + x2 = 0 + -65.625 Combine like terms: 65.625 + -65.625 = 0.000 0.000 + -0.5x + x2 = 0 + -65.625 -0.5x + x2 = 0 + -65.625 Combine like terms: 0 + -65.625 = -65.625 -0.5x + x2 = -65.625 The x term is -0.5x. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5x + 0.0625 + x2 = -65.625 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = -65.625 + 0.0625 Combine like terms: -65.625 + 0.0625 = -65.5625 0.0625 + -0.5x + x2 = -65.5625 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = -65.5625 Can't calculate square root of the right side. The solution to this equation could not be determined.
