| 16 | x | x | = | ( | 1 50 | − | x | ) | ( | 1 50 | − | x | ) |
| Right side of the equation = | 1 50 | ( | 1 50 | − | x | ) | − | x | ( | 1 50 | − | x | ) |
| = | 1 50 | × | 1 50 | − | 1 50 | x | − | x | ( | 1 50 | − | x | ) |
| = | 1 2500 | − | 1 50 | x | − | x | ( | 1 50 | − | x | ) |
| = | 1 2500 | − | 1 50 | x | − | x | × | 1 50 | + | x | x |
| = | 1 2500 | − | 1 25 | x | + | x | x |
| 16 | x | x | = | 1 2500 | − | 1 25 | x | + | x | x |
