Work: Find the solution of equation 5.98x3+16.46x2-273.25x-36.74 = 0 .
Question type: Equation
Solution:Original question:
299 50 | x | × | 3 | + | 823 50 | x | × | 2 | − | 1093 4 | x | − | 1837 50 | = | 0 |
| Left side of the equation = | 897 50 | x | + | 823 25 | x | − | 1093 4 | x | − | 1837 50 |
| = | - | 22239 100 | x | − | 1837 50 |
| - | 22239 100 | x | − | 1837 50 | = | 0 |
Transposition :
| - | 22239 100 | x | = | 0 | + | 1837 50 |
Combine the items on the right of the equation:
| - | 22239 100 | x | = | 1837 50 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
| - | 1837 50 | = | 22239 100 | 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 :
22239 100 | x | = | - | 1837 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 1837 50 | ÷ | 22239 100 |
| = | - | 1837 50 | × | 100 22239 |
| = | - | 1837 | × | 2 22239 |
We obtained :
| x | = | - | 3674 22239 |
Convert the result to decimal form :
| x | = | - 0.165205 |
