Work: Find the solution of equation 0.2428x3-3.5439x2+16.2726-23.364 = 0 .
Question type: Equation
Solution:Original question:
607 2500 | x | × | 3 | − | 35439 10000 | x | × | 2 | + | 81363 5000 | − | 5841 250 | = | 0 |
| Left side of the equation = | 1821 2500 | x | − | 35439 5000 | x | + | 81363 5000 | − | 5841 250 |
| = | - | 31797 5000 | x | − | 35457 5000 |
| - | 31797 5000 | x | − | 35457 5000 | = | 0 |
Transposition :
| - | 31797 5000 | x | = | 0 | + | 35457 5000 |
Combine the items on the right of the equation:
| - | 31797 5000 | x | = | 35457 5000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 35457 5000 | = | 31797 5000 | 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 :
31797 5000 | x | = | - | 35457 5000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 35457 5000 | ÷ | 31797 5000 |
| = | - | 35457 5000 | × | 5000 31797 |
| = | - | 11819 | × | 1 10599 |
We obtained :
| x | = | - | 11819 10599 |
Convert the result to decimal form :
| x | = | - 1.115105 |
