Work: Find the solution of equation 4h3+48h2+192h+256 = 197.309 .
Question type: Equation
Solution:Original question:
| 4 | h | × | 3 | + | 48 | h | × | 2 | + | 192 | h | + | 256 | = | 197309 1000 |
| Left side of the equation = | 12 | h | + | 96 | h | + | 192 | h | + | 256 |
| = | 300 | h | + | 256 |
| 300 | h | + | 256 | = | 197309 1000 |
Transposition :
| 300 | h | = | 197309 1000 | − | 256 |
Combine the items on the right of the equation:
| 300 | h | = | - | 58691 1000 |
The coefficient of the unknown number is reduced to 1 :
| h | = | - | 58691 1000 | ÷ | 300 |
| = | - | 58691 1000 | × | 1 300 |
We obtained :
| h | = | - | 58691 300000 |
Convert the result to decimal form :
| h | = | - 0.195637 |
