Work: Find the solution of equation 119.2*2 = （29+10.16*x-0.06）*（x-2.86） .
Question type: Equation
Solution:Original question:
596 5 | × | 2 | = | ( | 29 | + | 254 25 | x | − | 3 50 | ) | ( | x | − | 143 50 | ) |
| Left side of the equation = | 1192 5 |
1192 5 | = | ( | 29 | + | 254 25 | x | − | 3 50 | ) | ( | x | − | 143 50 | ) |
| Right side of the equation = | 29 | ( | x | − | 143 50 | ) | + | 254 25 | x | ( | x | − | 143 50 | ) | − | 3 50 | ( | x | − | 143 50 | ) |
| = | 29 | x | − | 29 | × | 143 50 | + | 254 25 | x | ( | x | − | 143 50 | ) | − | 3 50 | ( | x | − | 143 50 | ) |
| = | 29 | x | − | 4147 50 | + | 254 25 | x | ( | x | − | 143 50 | ) | − | 3 50 | ( | x | − | 143 50 | ) |
| = | 29 | x | − | 4147 50 | + | 254 25 | x | x | − | 254 25 | x | × | 143 50 | − | 3 50 | ( | x | − | 143 50 | ) |
| = | 29 | x | − | 4147 50 | + | 254 25 | x | x | − | 18161 625 | x | − | 3 50 | ( | x | − | 143 50 | ) |
| = | - | 36 625 | x | − | 4147 50 | + | 254 25 | x | x | − | 3 50 | ( | x | − | 143 50 | ) |
| = | - | 36 625 | x | − | 4147 50 | + | 254 25 | x | x | − | 3 50 | x | + | 3 50 | × | 143 50 |
| = | - | 36 625 | x | − | 4147 50 | + | 254 25 | x | x | − | 3 50 | x | + | 429 2500 |
| = | - | 147 1250 | x | − | 206921 2500 | + | 254 25 | x | x |
1192 5 | = | - | 147 1250 | x | − | 206921 2500 | + | 254 25 | x | x |
