Work: Find the solution of equation 49.272x2+595.56x+0.7763 = 0 .
Question type: Equation
Solution:Original question:
6159 125 | x | × | 2 | + | 14889 25 | x | + | 7763 10000 | = | 0 |
| Left side of the equation = | 12318 125 | x | + | 14889 25 | x | + | 7763 10000 |
| = | 86763 125 | x | + | 7763 10000 |
86763 125 | x | + | 7763 10000 | = | 0 |
Transposition :
86763 125 | x | = | 0 | − | 7763 10000 |
Combine the items on the right of the equation:
86763 125 | x | = | - | 7763 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 7763 10000 | ÷ | 86763 125 |
| = | - | 7763 10000 | × | 125 86763 |
| = | - | 7763 80 | × | 1 86763 |
We obtained :
| x | = | - | 7763 6941040 |
Convert the result to decimal form :
| x | = | - 0.001118 |
