Simplifying x2 + -23x + 437 = 0 Reorder the terms: 437 + -23x + x2 = 0 Solving 437 + -23x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-437' to each side of the equation. 437 + -23x + -437 + x2 = 0 + -437 Reorder the terms: 437 + -437 + -23x + x2 = 0 + -437 Combine like terms: 437 + -437 = 0 0 + -23x + x2 = 0 + -437 -23x + x2 = 0 + -437 Combine like terms: 0 + -437 = -437 -23x + x2 = -437 The x term is -23x. Take half its coefficient (-11.5). Square it (132.25) and add it to both sides. Add '132.25' to each side of the equation. -23x + 132.25 + x2 = -437 + 132.25 Reorder the terms: 132.25 + -23x + x2 = -437 + 132.25 Combine like terms: -437 + 132.25 = -304.75 132.25 + -23x + x2 = -304.75 Factor a perfect square on the left side: (x + -11.5)(x + -11.5) = -304.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
