| ( | x | − | 2 | ) | ÷ | 2 | × | x | − | x | ( | x | − | 2 | ) | ÷ | 8 | = | 1 |
| Left side of the equation = | x | × | 1 2 | x | − | 2 | × | 1 2 | x | − | x | ( | x | − | 2 | ) | × | 1 8 |
| = | x | × | 1 2 | x | − | 1 | x | − | x | ( | x | − | 2 | ) | × | 1 8 |
| = | x | × | 1 2 | x | − | 1 | x | − | x | x | × | 1 8 | + | x | × | 2 | × | 1 8 |
| = | x | × | 1 2 | x | − | 1 | x | − | x | x | × | 1 8 | + | x | × | 1 4 |
| = | x | × | 1 2 | x | − | 3 4 | x | − | x | x | × | 1 8 |
| x | × | 1 2 | x | − | 3 4 | x | − | x | x | × | 1 8 | = | 1 |
