Work: Find the solution of equation 1165 = 0.0353x2-2.7643x+262.24 .
Question type: Equation
Solution:Original question:
| 1165 | = | 353 10000 | x | × | 2 | − | 27643 10000 | x | + | 6556 25 |
| Right side of the equation = | 353 5000 | x | − | 27643 10000 | x | + | 6556 25 |
| = | - | 26937 10000 | x | + | 6556 25 |
| 1165 | = | - | 26937 10000 | x | + | 6556 25 |
Transposition :
26937 10000 | x | = | 6556 25 | − | 1165 |
Combine the items on the right of the equation:
26937 10000 | x | = | - | 22569 25 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 22569 25 | ÷ | 26937 10000 |
| = | - | 22569 25 | × | 10000 26937 |
| = | - | 7523 | × | 400 8979 |
We obtained :
| x | = | - | 3009200 8979 |
Convert the result to decimal form :
| x | = | - 335.137543 |
