( | x | − | 3 | ) | ( | x | − | 1 | ÷ | 5 | ) | = | 0 |
Left side of the equation = | x | ( | x | − | 1 | ÷ | 5 | ) | − | 3 | ( | x | − | 1 | ÷ | 5 | ) |
= | x | x | − | x | × | 1 | ÷ | 5 | − | 3 | ( | x | − | 1 | ÷ | 5 | ) |
= | x | x | − | x | × | 1 5 | − | 3 | ( | x | − | 1 | ÷ | 5 | ) |
= | x | x | − | 1 5 | x | − | 3 | x | + | 3 | × | 1 | ÷ | 5 |
= | x | x | − | 1 5 | x | − | 3 | x | + | 3 5 |
= | x | x | − | 16 5 | x | + | 3 5 |
x | x | − | 16 5 | x | + | 3 5 | = | 0 |
x1= | 1 5 |
x2=3 |
