Work: Find the solution of equation 2.43x-0.46 = 0.0394x3-0.2959x2+1.2564x .
Question type: Equation
Solution:Original question:
243 100 | x | − | 23 50 | = | 197 5000 | x | × | 3 | − | 2959 10000 | x | × | 2 | + | 3141 2500 | x |
| Right side of the equation = | 591 5000 | x | − | 2959 5000 | x | + | 3141 2500 | x |
| = | 1957 2500 | x |
243 100 | x | − | 23 50 | = | 1957 2500 | x |
Transposition :
243 100 | x | − | 1957 2500 | x | = | 23 50 |
Combine the items on the left of the equation:
2059 1250 | x | = | 23 50 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 23 50 | ÷ | 2059 1250 |
| = | 23 50 | × | 1250 2059 |
| = | 23 | × | 25 2059 |
We obtained :
| x | = | 575 2059 |
Convert the result to decimal form :
| x | = | 0.279262 |
