Work: Find the solution of equation -0.3119x2+406.82x-131677 = 0 .
Question type: Equation
Solution:Original question:
| - | 3119 10000 | x | × | 2 | + | 20341 50 | x | − | 131677 | = | 0 |
| Left side of the equation = | - | 3119 5000 | x | + | 20341 50 | x | − | 131677 |
| = | 2030981 5000 | x | − | 131677 |
2030981 5000 | x | − | 131677 | = | 0 |
Transposition :
2030981 5000 | x | = | 0 | + | 131677 |
Combine the items on the right of the equation:
2030981 5000 | x | = | 131677 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 131677 | ÷ | 2030981 5000 |
| = | 131677 | × | 5000 2030981 |
We obtained :
| x | = | 658385000 2030981 |
Convert the result to decimal form :
| x | = | 324.17093 |
