1 4 | x | + | x | x | = | 9 5 | × | 1 100000 | ( | 1 20 | − | x | ) |
| Right side of the equation = | 9 500000 | ( | 1 20 | − | x | ) |
1 4 | x | + | x | x | = | 9 500000 | ( | 1 20 | − | x | ) |
| Right side of the equation = | 9 500000 | × | 1 20 | − | 9 500000 | x |
| = | 9 10000000 | − | 9 500000 | x |
1 4 | x | + | x | x | = | 9 10000000 | − | 9 500000 | x |
| x1=0 | , it is the incremental root of the eqution. |
