Work: Find the solution of equation 4.637x2+8.2158x-28.01632 = 0 .
Question type: Equation
Solution:Original question:
4637 1000 | x | × | 2 | + | 41079 5000 | x | − | 87551 3125 | = | 0 |
| Left side of the equation = | 4637 500 | x | + | 41079 5000 | x | − | 87551 3125 |
| = | 87449 5000 | x | − | 87551 3125 |
87449 5000 | x | − | 87551 3125 | = | 0 |
Transposition :
87449 5000 | x | = | 0 | + | 87551 3125 |
Combine the items on the right of the equation:
87449 5000 | x | = | 87551 3125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 87551 3125 | ÷ | 87449 5000 |
| = | 87551 3125 | × | 5000 87449 |
| = | 87551 5 | × | 8 87449 |
We obtained :
| x | = | 700408 437245 |
Convert the result to decimal form :
| x | = | 1.601866 |
