Work: Find the solution of equation 5.17x-1.348 = -0.2393x2+1.2382x .
Question type: Equation
Solution:Original question:
517 100 | x | − | 337 250 | = | - | 2393 10000 | x | × | 2 | + | 6191 5000 | x |
| Right side of the equation = | - | 2393 5000 | x | + | 6191 5000 | x |
| = | 1899 2500 | x |
517 100 | x | − | 337 250 | = | 1899 2500 | x |
Transposition :
517 100 | x | − | 1899 2500 | x | = | 337 250 |
Combine the items on the left of the equation:
5513 1250 | x | = | 337 250 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 337 250 | ÷ | 5513 1250 |
| = | 337 250 | × | 1250 5513 |
| = | 337 | × | 5 5513 |
We obtained :
| x | = | 1685 5513 |
Convert the result to decimal form :
| x | = | 0.305641 |
