Simplifying x2 + -18x + 81 = -256 Reorder the terms: 81 + -18x + x2 = -256 Solving 81 + -18x + x2 = -256 Solving for variable 'x'. Reorder the terms: 81 + 256 + -18x + x2 = -256 + 256 Combine like terms: 81 + 256 = 337 337 + -18x + x2 = -256 + 256 Combine like terms: -256 + 256 = 0 337 + -18x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-337' to each side of the equation. 337 + -18x + -337 + x2 = 0 + -337 Reorder the terms: 337 + -337 + -18x + x2 = 0 + -337 Combine like terms: 337 + -337 = 0 0 + -18x + x2 = 0 + -337 -18x + x2 = 0 + -337 Combine like terms: 0 + -337 = -337 -18x + x2 = -337 The x term is -18x. Take half its coefficient (-9). Square it (81) and add it to both sides. Add '81' to each side of the equation. -18x + 81 + x2 = -337 + 81 Reorder the terms: 81 + -18x + x2 = -337 + 81 Combine like terms: -337 + 81 = -256 81 + -18x + x2 = -256 Factor a perfect square on the left side: (x + -9)(x + -9) = -256 Can't calculate square root of the right side. The solution to this equation could not be determined.
