Work: Find the solution of equation -37.852x6+128.88x5-171.88x4+114.08x3-39.244x2+6.9673x+0.0333 = 0 .
Question type: Equation
Solution:Original question:
| - | 9463 250 | x | × | 6 | + | 3222 25 | x | × | 5 | − | 4297 25 | x | × | 4 | + | 2852 25 | x | × | 3 | = | 0 |
| Left side of the equation = | - | 28389 125 | x | + | 3222 5 | x | − | 17188 25 | x | + | 8556 25 | x | − | 9811 125 | x | + | 69673 10000 | x |
| = | 4873 10000 | x | + | 333 10000 |
4873 10000 | x | + | 333 10000 | = | 0 |
Transposition :
4873 10000 | x | = | 0 | − | 333 10000 |
Combine the items on the right of the equation:
4873 10000 | x | = | - | 333 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 333 10000 | ÷ | 4873 10000 |
| = | - | 333 10000 | × | 10000 4873 |
| = | - | 333 | × | 1 4873 |
We obtained :
| x | = | - | 333 4873 |
Convert the result to decimal form :
| x | = | - 0.068336 |
