[ 1/1 Equation]
Work: Find the solution of equation 11.13228x2-22.032x-514.8 = 0 .
Question type: Equation
Solution:Original question:
278307 25000 | x | × | 2 | − | 2754 125 | x | − | 2574 5 | = | 0 |
| Left side of the equation = | 278307 12500 | x | − | 2754 125 | x | − | 2574 5 |
| = | 2907 12500 | x | − | 2574 5 |
2907 12500 | x | − | 2574 5 | = | 0 |
Transposition :
2907 12500 | x | = | 0 | + | 2574 5 |
Combine the items on the right of the equation:
2907 12500 | x | = | 2574 5 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 2574 5 | ÷ | 2907 12500 |
| = | 2574 5 | × | 12500 2907 |
| = | 286 | × | 2500 323 |
We obtained :
| x | = | 715000 323 |
Convert the result to decimal form :
| x | = | 2213.622291 |
