Simplifying x2 + -2x + 84 = 0 Reorder the terms: 84 + -2x + x2 = 0 Solving 84 + -2x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-84' to each side of the equation. 84 + -2x + -84 + x2 = 0 + -84 Reorder the terms: 84 + -84 + -2x + x2 = 0 + -84 Combine like terms: 84 + -84 = 0 0 + -2x + x2 = 0 + -84 -2x + x2 = 0 + -84 Combine like terms: 0 + -84 = -84 -2x + x2 = -84 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 = -84 + 1 Reorder the terms: 1 + -2x + x2 = -84 + 1 Combine like terms: -84 + 1 = -83 1 + -2x + x2 = -83 Factor a perfect square on the left side: (x + -1)(x + -1) = -83 Can't calculate square root of the right side. The solution to this equation could not be determined.
