Work: Find the solution of equation -0.0059x2+0.0688x+1.3586 = 1.4223 .
Question type: Equation
Solution:Original question:
| - | 59 10000 | x | × | 2 | + | 43 625 | x | + | 6793 5000 | = | 14223 10000 |
| Left side of the equation = | - | 59 5000 | x | + | 43 625 | x | + | 6793 5000 |
| = | 57 1000 | x | + | 6793 5000 |
57 1000 | x | + | 6793 5000 | = | 14223 10000 |
Transposition :
57 1000 | x | = | 14223 10000 | − | 6793 5000 |
Combine the items on the right of the equation:
57 1000 | x | = | 637 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 637 10000 | ÷ | 57 1000 |
| = | 637 10000 | × | 1000 57 |
| = | 637 10 | × | 1 57 |
We obtained :
| x | = | 637 570 |
Convert the result to decimal form :
| x | = | 1.117544 |
