x | x | = | 13 5 | ( | 1 | − | x | ) | ( | 3 | − | x | ) |
Right side of the equation = | 13 5 | × | 1 | ( | 3 | − | x | ) | − | 13 5 | x | ( | 3 | − | x | ) |
= | 13 5 | ( | 3 | − | x | ) | − | 13 5 | x | ( | 3 | − | x | ) |
= | 13 5 | × | 3 | − | 13 5 | x | − | 13 5 | x | ( | 3 | − | x | ) |
= | 39 5 | − | 13 5 | x | − | 13 5 | x | ( | 3 | − | x | ) |
= | 39 5 | − | 13 5 | x | − | 13 5 | x | × | 3 | + | 13 5 | x | x |
= | 39 5 | − | 13 5 | x | − | 39 5 | x | + | 13 5 | x | x |
= | 39 5 | − | 52 5 | x | + | 13 5 | x | x |
x | x | = | 39 5 | − | 52 5 | x | + | 13 5 | x | x |
