Simplifying x = x2 + 23 Reorder the terms: x = 23 + x2 Solving x = 23 + x2 Solving for variable 'x'. Reorder the terms: -23 + x + -1x2 = 23 + x2 + -23 + -1x2 Reorder the terms: -23 + x + -1x2 = 23 + -23 + x2 + -1x2 Combine like terms: 23 + -23 = 0 -23 + x + -1x2 = 0 + x2 + -1x2 -23 + x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -23 + x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 23 + -1x + x2 = 0 Move the constant term to the right: Add '-23' to each side of the equation. 23 + -1x + -23 + x2 = 0 + -23 Reorder the terms: 23 + -23 + -1x + x2 = 0 + -23 Combine like terms: 23 + -23 = 0 0 + -1x + x2 = 0 + -23 -1x + x2 = 0 + -23 Combine like terms: 0 + -23 = -23 -1x + x2 = -23 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = -23 + 0.25 Reorder the terms: 0.25 + -1x + x2 = -23 + 0.25 Combine like terms: -23 + 0.25 = -22.75 0.25 + -1x + x2 = -22.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -22.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
