| Right side of the equation = | 1 | ( | - | 1 2 | x | + | 3 5 | ) | + | 3 2 | x | ( | - | 1 2 | x | + | 3 5 | ) |
| = | - | 1 | × | 1 2 | x | + | 1 | × | 3 5 | + | 3 2 | x | ( | - | 1 2 | x | + | 3 5 | ) |
| = | - | 1 2 | x | + | 3 5 | + | 3 2 | x | ( | - | 1 2 | x | + | 3 5 | ) |
| = | - | 1 2 | x | + | 3 5 | − | 3 2 | x | × | 1 2 | x | + | 3 2 | x | × | 3 5 |
