Work: Find the solution of equation (0.00005-x)*(0.0004-2*x)*(0.0004-2*x) = (0.0000425-x)*(0.000275-x)*(0.000275-x) .
Question type: Equation
Solution:Original question:
| ( | 1 20000 | − | x | ) | ( | 1 2500 | − | 2 | x | ) | ( | 1 2500 | − | 2 | x | ) | = | ( | 17 400000 | − | x | ) | ( | 11 40000 | − | x | ) | ( | 11 40000 | − | x | ) |
| Left side of the equation = | 1 20000 | ( | 1 2500 | − | 2 | x | ) | ( | 1 2500 | − | 2 | x | ) | − | x | ( | 1 2500 | − | 2 | x | ) | ( | 1 2500 | − | 2 | x | ) |
| = | 1 20000 | × | 1 2500 | ( | 1 2500 | − | 2 | x | ) | − | 1 20000 | × | 2 | x | ( | 1 2500 | − | 2 | x | ) | − | x | ( | 1 2500 | − | 2 | x | ) | ( | 1 2500 | − | 2 | x | ) |
| = | 1 50000000 | ( | 1 2500 | − | 2 | x | ) | − | 1 10000 | x | ( | 1 2500 | − | 2 | x | ) | − | x | ( | 1 2500 | − | 2 | x | ) | ( | 1 2500 | − | 2 | x | ) |
| = | 1 50000000 | × | 1 2500 | − | 1 50000000 | × | 2 | x | − | 1 10000 | x | ( | 1 2500 | − | 2 | x | ) | − | x | ( | 1 2500 | − | 2 | x | ) | ( | 1 2500 | − | 2 | x | ) |
x=0, it is the incremental root of the eqution.
