[ 1/1 Equation]
Work: Find the solution of equation 10.1448X2-53.88X+72.805 = 0 .
Question type: Equation
Solution:Original question:
12681 1250 | X | × | 2 | − | 1347 25 | X | + | 14561 200 | = | 0 |
| Left side of the equation = | 12681 625 | X | − | 1347 25 | X | + | 14561 200 |
| = | - | 20994 625 | X | + | 14561 200 |
| - | 20994 625 | X | + | 14561 200 | = | 0 |
Transposition :
| - | 20994 625 | X | = | 0 | − | 14561 200 |
Combine the items on the right of the equation:
| - | 20994 625 | X | = | - | 14561 200 |
By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
14561 200 | = | 20994 625 | 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 :
20994 625 | X | = | 14561 200 |
The coefficient of the unknown number is reduced to 1 :
| X | = | 14561 200 | ÷ | 20994 625 |
| = | 14561 200 | × | 625 20994 |
| = | 14561 8 | × | 25 20994 |
We obtained :
| X | = | 364025 167952 |
Convert the result to decimal form :
| X | = | 2.167435 |
