Work: Find the solution of equation (2.19-1.5*x)*(4.38-x) = 0.008226 .
Question type: Equation
Solution:Original question:
| ( | 219 100 | − | 3 2 | x | ) | ( | 219 50 | − | x | ) | = | 4113 500000 |
| Left side of the equation = | 219 100 | ( | 219 50 | − | x | ) | − | 3 2 | x | ( | 219 50 | − | x | ) |
| = | 219 100 | × | 219 50 | − | 219 100 | x | − | 3 2 | x | ( | 219 50 | − | x | ) |
| = | 47961 5000 | − | 219 100 | x | − | 3 2 | x | ( | 219 50 | − | x | ) |
| = | 47961 5000 | − | 219 100 | x | − | 3 2 | x | × | 219 50 | + | 3 2 | x | x |
| = | 47961 5000 | − | 219 100 | x | − | 657 100 | x | + | 3 2 | x | x |
| = | 47961 5000 | − | 219 25 | x | + | 3 2 | x | x |
47961 5000 | − | 219 25 | x | + | 3 2 | x | x | = | 4113 500000 |
The solution of the equation:
x1≈1.458123 , keep 6 decimal places
x2≈4.381877 , keep 6 decimal places
There are 2 solution(s).
