Work: Find the solution of equation 0.0006x4-0.0135x3+0.0966x2-0.233x+2.2985 = 0 .
Question type: Equation
Solution:Original question:
3 5000 | x | × | 4 | − | 27 2000 | x | × | 3 | + | 483 5000 | x | × | 2 | − | 233 1000 | x | + | 4597 2000 | = | 0 |
| Left side of the equation = | 3 1250 | x | − | 81 2000 | x | + | 483 2500 | x | − | 233 1000 | x | + | 4597 2000 |
| = | - | 779 10000 | x | + | 4597 2000 |
| - | 779 10000 | x | + | 4597 2000 | = | 0 |
Transposition :
| - | 779 10000 | x | = | 0 | − | 4597 2000 |
Combine the items on the right of the equation:
| - | 779 10000 | x | = | - | 4597 2000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
4597 2000 | = | 779 10000 | x |
If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
779 10000 | x | = | 4597 2000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 4597 2000 | ÷ | 779 10000 |
| = | 4597 2000 | × | 10000 779 |
| = | 4597 | × | 5 779 |
We obtained :
| x | = | 22985 779 |
Convert the result to decimal form :
| x | = | 29.505777 |
