( | 8 | + | 12 | x | ) | ( | x | − | 1 2 | ) | = | 119 5 | x |
Left side of the equation = | 8 | ( | x | − | 1 2 | ) | + | 12 | x | ( | x | − | 1 2 | ) |
= | 8 | x | − | 8 | × | 1 2 | + | 12 | x | ( | x | − | 1 2 | ) |
= | 8 | x | − | 4 | + | 12 | x | ( | x | − | 1 2 | ) |
= | 8 | x | − | 4 | + | 12 | x | x | − | 12 | x | × | 1 2 |
= | 8 | x | − | 4 | + | 12 | x | x | − | 6 | x |
= | 2 | x | − | 4 | + | 12 | x | x |
2 | x | − | 4 | + | 12 | x | x | = | 119 5 | x |
