Work: Find the solution of equation 48.1975x2+7.27x-137.59 = 0 .
Question type: Equation
Solution:Original question:
19279 400 | x | × | 2 | + | 727 100 | x | − | 13759 100 | = | 0 |
| Left side of the equation = | 19279 200 | x | + | 727 100 | x | − | 13759 100 |
| = | 20733 200 | x | − | 13759 100 |
20733 200 | x | − | 13759 100 | = | 0 |
Transposition :
20733 200 | x | = | 0 | + | 13759 100 |
Combine the items on the right of the equation:
20733 200 | x | = | 13759 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 13759 100 | ÷ | 20733 200 |
| = | 13759 100 | × | 200 20733 |
| = | 13759 | × | 2 20733 |
We obtained :
| x | = | 27518 20733 |
Convert the result to decimal form :
| x | = | 1.327256 |
