Work: Find the solution of equation 0 = 0.0925x2-0.6695x+1.1625 .
Question type: Equation
Solution:Original question:
| 0 | = | 37 400 | x | × | 2 | − | 1339 2000 | x | + | 93 80 |
| Right side of the equation = | 37 200 | x | − | 1339 2000 | x | + | 93 80 |
| = | - | 969 2000 | x | + | 93 80 |
| 0 | = | - | 969 2000 | x | + | 93 80 |
Transposition :
969 2000 | x | = | 93 80 | − | 0 |
Combine the items on the right of the equation:
969 2000 | x | = | 93 80 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 93 80 | ÷ | 969 2000 |
| = | 93 80 | × | 2000 969 |
| = | 31 | × | 25 323 |
We obtained :
| x | = | 775 323 |
Convert the result to decimal form :
| x | = | 2.399381 |
