Work: Find the solution of equation (x+0.186)*x = 2.21*(0.062-x)*(0.8755-x) .
Question type: Equation
Solution:Original question:
| ( | x | + | 93 500 | ) | x | = | 221 100 | ( | 31 500 | − | x | ) | ( | 1751 2000 | − | x | ) |
| Left side of the equation = | x | x | + | 93 500 | x |
| x | x | + | 93 500 | x | = | 221 100 | ( | 31 500 | − | x | ) | ( | 1751 2000 | − | x | ) |
| Right side of the equation = | 221 100 | × | 31 500 | ( | 1751 2000 | − | x | ) | − | 221 100 | x | ( | 1751 2000 | − | x | ) |
| = | 6851 50000 | ( | 1751 2000 | − | x | ) | − | 221 100 | x | ( | 1751 2000 | − | x | ) |
| = | 6851 50000 | × | 1751 2000 | − | 6851 50000 | x | − | 221 100 | x | ( | 1751 2000 | − | x | ) |
| = | 11996101 100000000 | − | 6851 50000 | x | − | 221 100 | x | ( | 1751 2000 | − | x | ) |
| = | 11996101 100000000 | − | 6851 50000 | x | − | 221 100 | x | × | 1751 2000 | + | 221 100 | x | x |
| = | 11996101 100000000 | − | 6851 50000 | x | − | 386971 200000 | x | + | 221 100 | x | x |
