| t | = | ( | t | + | 3 | ) | ( | t | + | 3 | ) | − | 2 | t | − | 3 |
| Right side of the equation = | t | ( | t | + | 3 | ) | + | 3 | ( | t | + | 3 | ) | − | 2 | t | − | 3 |
| = | t | t | + | t | × | 3 | + | 3 | ( | t | + | 3 | ) | − | 2 | t | − | 3 |
| = | t | t | + | 1 | t | + | 3 | ( | t | + | 3 | ) | − | 3 |
| = | t | t | + | 1 | t | + | 3 | t | + | 3 | × | 3 | − | 3 |
| = | t | t | + | 1 | t | + | 3 | t | + | 9 | − | 3 |
| = | t | t | + | 4 | t | + | 6 |
| t | = | t | t | + | 4 | t | + | 6 |
