Work: Find the solution of equation 0.0427x2+0.0929x+1.3332 = 1.3699 .
Question type: Equation
Solution:Original question:
427 10000 | x | × | 2 | + | 929 10000 | x | + | 3333 2500 | = | 13699 10000 |
| Left side of the equation = | 427 5000 | x | + | 929 10000 | x | + | 3333 2500 |
| = | 1783 10000 | x | + | 3333 2500 |
1783 10000 | x | + | 3333 2500 | = | 13699 10000 |
Transposition :
1783 10000 | x | = | 13699 10000 | − | 3333 2500 |
Combine the items on the right of the equation:
1783 10000 | x | = | 367 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 367 10000 | ÷ | 1783 10000 |
| = | 367 10000 | × | 10000 1783 |
| = | 367 | × | 1 1783 |
We obtained :
| x | = | 367 1783 |
Convert the result to decimal form :
| x | = | 0.205833 |
