Work: Find the solution of equation 3.0896x2-4.3986x+3.0896 = 0 .
Question type: Equation
Solution:Original question:
1931 625 | x | × | 2 | − | 21993 5000 | x | + | 1931 625 | = | 0 |
| Left side of the equation = | 3862 625 | x | − | 21993 5000 | x | + | 1931 625 |
| = | 8903 5000 | x | + | 1931 625 |
8903 5000 | x | + | 1931 625 | = | 0 |
Transposition :
8903 5000 | x | = | 0 | − | 1931 625 |
Combine the items on the right of the equation:
8903 5000 | x | = | - | 1931 625 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 1931 625 | ÷ | 8903 5000 |
| = | - | 1931 625 | × | 5000 8903 |
| = | - | 1931 | × | 8 8903 |
We obtained :
| x | = | - | 15448 8903 |
Convert the result to decimal form :
| x | = | - 1.735145 |
