[ 1/1 Equation]
Work: Find the solution of equation x3-4.72334x2+0.5143 = 0 .
Question type: Equation
Solution:Original question:
| x | × | 3 | − | 236167 50000 | x | × | 2 | + | 5143 10000 | = | 0 |
| Left side of the equation = | x | × | 3 | − | 236167 25000 | x | + | 5143 10000 |
| = | - | 161167 25000 | x | + | 5143 10000 |
| - | 161167 25000 | x | + | 5143 10000 | = | 0 |
Transposition :
| - | 161167 25000 | x | = | 0 | − | 5143 10000 |
Combine the items on the right of the equation:
| - | 161167 25000 | x | = | - | 5143 10000 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
5143 10000 | = | 161167 25000 | 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 :
161167 25000 | x | = | 5143 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 5143 10000 | ÷ | 161167 25000 |
| = | 5143 10000 | × | 25000 161167 |
| = | 5143 2 | × | 5 161167 |
We obtained :
| x | = | 25715 322334 |
Convert the result to decimal form :
| x | = | 0.079777 |
