( | x | − | 100 | ) | ( | - | 20 | x | + | 340 | ) | = | 24000 |
Left side of the equation = | x | ( | - | 20 | x | + | 340 | ) | − | 100 | ( | - | 20 | x | + | 340 | ) |
= | - | x | × | 20 | x | + | x | × | 340 | − | 100 | ( | - | 20 | x | + | 340 | ) |
= | - | x | × | 20 | x | + | 340 | x | + | 100 | × | 20 | x | − | 100 | × | 340 |
= | - | x | × | 20 | x | + | 340 | x | + | 2000 | x | − | 34000 |
= | - | x | × | 20 | x | + | 2340 | x | − | 34000 |
- | x | × | 20 | x | + | 2340 | x | − | 34000 | = | 24000 |
