Simplifying x2 + -25x + 305 = 0 Reorder the terms: 305 + -25x + x2 = 0 Solving 305 + -25x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-305' to each side of the equation. 305 + -25x + -305 + x2 = 0 + -305 Reorder the terms: 305 + -305 + -25x + x2 = 0 + -305 Combine like terms: 305 + -305 = 0 0 + -25x + x2 = 0 + -305 -25x + x2 = 0 + -305 Combine like terms: 0 + -305 = -305 -25x + x2 = -305 The x term is -25x. Take half its coefficient (-12.5). Square it (156.25) and add it to both sides. Add '156.25' to each side of the equation. -25x + 156.25 + x2 = -305 + 156.25 Reorder the terms: 156.25 + -25x + x2 = -305 + 156.25 Combine like terms: -305 + 156.25 = -148.75 156.25 + -25x + x2 = -148.75 Factor a perfect square on the left side: (x + -12.5)(x + -12.5) = -148.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
