Simplifying x2 + 36x + 572 = 0 Reorder the terms: 572 + 36x + x2 = 0 Solving 572 + 36x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-572' to each side of the equation. 572 + 36x + -572 + x2 = 0 + -572 Reorder the terms: 572 + -572 + 36x + x2 = 0 + -572 Combine like terms: 572 + -572 = 0 0 + 36x + x2 = 0 + -572 36x + x2 = 0 + -572 Combine like terms: 0 + -572 = -572 36x + x2 = -572 The x term is 36x. Take half its coefficient (18). Square it (324) and add it to both sides. Add '324' to each side of the equation. 36x + 324 + x2 = -572 + 324 Reorder the terms: 324 + 36x + x2 = -572 + 324 Combine like terms: -572 + 324 = -248 324 + 36x + x2 = -248 Factor a perfect square on the left side: (x + 18)(x + 18) = -248 Can't calculate square root of the right side. The solution to this equation could not be determined.
