Work: Find the solution of equation 42362x2-36763x+7851.3 = 0 .
Question type: Equation
Solution:Original question:
| 42362 | x | × | 2 | − | 36763 | x | + | 78513 10 | = | 0 |
| Left side of the equation = | 84724 | x | − | 36763 | x | + | 78513 10 |
| = | 47961 | x | + | 78513 10 |
| 47961 | x | + | 78513 10 | = | 0 |
Transposition :
| 47961 | x | = | 0 | − | 78513 10 |
Combine the items on the right of the equation:
| 47961 | x | = | - | 78513 10 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 78513 10 | ÷ | 47961 |
| = | - | 78513 10 | × | 1 47961 |
| = | - | 26171 10 | × | 1 15987 |
We obtained :
| x | = | - | 26171 159870 |
Convert the result to decimal form :
| x | = | - 0.163702 |
