| x | ( | x | − | 2 | ) | = | ( | 34 | − | x | ) | ( | 16 | − | x | ) |
| 方程左边 = | x | x | − | x | × | 2 |
| x | x | − | 2 | x | = | ( | 34 | − | x | ) | ( | 16 | − | x | ) |
| 方程右边 = | 34 | ( | 16 | − | x | ) | − | x | ( | 16 | − | x | ) |
| = | 34 | × | 16 | − | 34 | x | − | x | ( | 16 | − | x | ) |
| = | 544 | − | 34 | x | − | x | ( | 16 | − | x | ) |
| = | 544 | − | 34 | x | − | x | × | 16 | + | x | x |
| = | 544 | − | 50 | x | + | x | x |
| x | x | − | 2 | x | = | 544 | − | 50 | x | + | x | x |
| x= | 34 3 |
