Work: Find the solution of equation -0.0932x3+1.1241x2-3.777x+2.5467 = 0 .
Question type: Equation
Solution:Original question:
| - | 233 2500 | x | × | 3 | + | 11241 10000 | x | × | 2 | − | 3777 1000 | x | + | 25467 10000 | = | 0 |
| Left side of the equation = | - | 699 2500 | x | + | 11241 5000 | x | − | 3777 1000 | x | + | 25467 10000 |
| = | - | 4521 2500 | x | + | 25467 10000 |
| - | 4521 2500 | x | + | 25467 10000 | = | 0 |
Transposition :
| - | 4521 2500 | x | = | 0 | − | 25467 10000 |
Combine the items on the right of the equation:
| - | 4521 2500 | x | = | - | 25467 10000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
25467 10000 | = | 4521 2500 | 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 :
4521 2500 | x | = | 25467 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 25467 10000 | ÷ | 4521 2500 |
| = | 25467 10000 | × | 2500 4521 |
| = | 8489 4 | × | 1 1507 |
We obtained :
| x | = | 8489 6028 |
Convert the result to decimal form :
| x | = | 1.408261 |
