| ( | x | − | 1000 | ) | ( | x | − | 2000 | ) | + | 2022 | = | 0 |
| Left side of the equation = | x | ( | x | − | 2000 | ) | − | 1000 | ( | x | − | 2000 | ) | + | 2022 |
| = | x | x | − | x | × | 2000 | − | 1000 | ( | x | − | 2000 | ) | + | 2022 |
| = | x | x | − | 2000 | x | − | 1000 | x | + | 1000 | × | 2000 | + | 2022 |
| = | x | x | − | 2000 | x | − | 1000 | x | + | 2000000 | + | 2022 |
| = | x | x | − | 3000 | x | + | 2002022 |
