Simplifying x2 + -36 + 324 + x2 + -2x + -1 = x2 Reorder the terms: -36 + 324 + -1 + -2x + x2 + x2 = x2 Combine like terms: -36 + 324 = 288 288 + -1 + -2x + x2 + x2 = x2 Combine like terms: 288 + -1 = 287 287 + -2x + x2 + x2 = x2 Combine like terms: x2 + x2 = 2x2 287 + -2x + 2x2 = x2 Solving 287 + -2x + 2x2 = x2 Solving for variable 'x'. Combine like terms: 2x2 + -1x2 = 1x2 287 + -2x + 1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 287 + -2x + 1x2 = 0 Begin completing the square. Move the constant term to the right: Add '-287' to each side of the equation. 287 + -2x + -287 + x2 = 0 + -287 Reorder the terms: 287 + -287 + -2x + x2 = 0 + -287 Combine like terms: 287 + -287 = 0 0 + -2x + x2 = 0 + -287 -2x + x2 = 0 + -287 Combine like terms: 0 + -287 = -287 -2x + x2 = -287 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = -287 + 1 Reorder the terms: 1 + -2x + x2 = -287 + 1 Combine like terms: -287 + 1 = -286 1 + -2x + x2 = -286 Factor a perfect square on the left side: (x + -1)(x + -1) = -286 Can't calculate square root of the right side. The solution to this equation could not be determined.
