Work: Find the solution of equation 3.37 = -0.0906x3-1.6087x2-7.3493x-2.5662 .
Question type: Equation
Solution:Original question:
337 100 | = | - | 453 5000 | x | × | 3 | − | 16087 10000 | x | × | 2 | − | 73493 10000 | x | − | 12831 5000 |
| Right side of the equation = | - | 1359 5000 | x | − | 16087 5000 | x | − | 73493 10000 | x | − | 12831 5000 |
| = | - | 21677 2000 | x | − | 12831 5000 |
337 100 | = | - | 21677 2000 | x | − | 12831 5000 |
Transposition :
21677 2000 | x | = | - | 12831 5000 | − | 337 100 |
Combine the items on the right of the equation:
21677 2000 | x | = | - | 29681 5000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 29681 5000 | ÷ | 21677 2000 |
| = | - | 29681 5000 | × | 2000 21677 |
| = | - | 29681 5 | × | 2 21677 |
We obtained :
| x | = | - | 59362 108385 |
Convert the result to decimal form :
| x | = | - 0.547696 |
