Simplifying 4x2 + -50x + 625 = 0 Reorder the terms: 625 + -50x + 4x2 = 0 Solving 625 + -50x + 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'. 156.25 + -12.5x + x2 = 0 Move the constant term to the right: Add '-156.25' to each side of the equation. 156.25 + -12.5x + -156.25 + x2 = 0 + -156.25 Reorder the terms: 156.25 + -156.25 + -12.5x + x2 = 0 + -156.25 Combine like terms: 156.25 + -156.25 = 0.00 0.00 + -12.5x + x2 = 0 + -156.25 -12.5x + x2 = 0 + -156.25 Combine like terms: 0 + -156.25 = -156.25 -12.5x + x2 = -156.25 The x term is -12.5x. Take half its coefficient (-6.25). Square it (39.0625) and add it to both sides. Add '39.0625' to each side of the equation. -12.5x + 39.0625 + x2 = -156.25 + 39.0625 Reorder the terms: 39.0625 + -12.5x + x2 = -156.25 + 39.0625 Combine like terms: -156.25 + 39.0625 = -117.1875 39.0625 + -12.5x + x2 = -117.1875 Factor a perfect square on the left side: (x + -6.25)(x + -6.25) = -117.1875 Can't calculate square root of the right side. The solution to this equation could not be determined.
