Simplifying x2 + -12.5x + 50 = 0 Reorder the terms: 50 + -12.5x + x2 = 0 Solving 50 + -12.5x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-50' to each side of the equation. 50 + -12.5x + -50 + x2 = 0 + -50 Reorder the terms: 50 + -50 + -12.5x + x2 = 0 + -50 Combine like terms: 50 + -50 = 0 0 + -12.5x + x2 = 0 + -50 -12.5x + x2 = 0 + -50 Combine like terms: 0 + -50 = -50 -12.5x + x2 = -50 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 = -50 + 39.0625 Reorder the terms: 39.0625 + -12.5x + x2 = -50 + 39.0625 Combine like terms: -50 + 39.0625 = -10.9375 39.0625 + -12.5x + x2 = -10.9375 Factor a perfect square on the left side: (x + -6.25)(x + -6.25) = -10.9375 Can't calculate square root of the right side. The solution to this equation could not be determined.
