Simplifying x2 + -2x + 87 = 0 Reorder the terms: 87 + -2x + x2 = 0 Solving 87 + -2x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-87' to each side of the equation. 87 + -2x + -87 + x2 = 0 + -87 Reorder the terms: 87 + -87 + -2x + x2 = 0 + -87 Combine like terms: 87 + -87 = 0 0 + -2x + x2 = 0 + -87 -2x + x2 = 0 + -87 Combine like terms: 0 + -87 = -87 -2x + x2 = -87 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 = -87 + 1 Reorder the terms: 1 + -2x + x2 = -87 + 1 Combine like terms: -87 + 1 = -86 1 + -2x + x2 = -86 Factor a perfect square on the left side: (x + -1)(x + -1) = -86 Can't calculate square root of the right side. The solution to this equation could not be determined.
