[ 1/1 Equation]
Work: Find the solution of equation -0.0216x2+0.0931x+1.3543 = 1.3576 .
Question type: Equation
Solution:Original question:
| - | 27 1250 | x | × | 2 | + | 931 10000 | x | + | 13543 10000 | = | 1697 1250 |
| Left side of the equation = | - | 27 625 | x | + | 931 10000 | x | + | 13543 10000 |
| = | 499 10000 | x | + | 13543 10000 |
499 10000 | x | + | 13543 10000 | = | 1697 1250 |
Transposition :
499 10000 | x | = | 1697 1250 | − | 13543 10000 |
Combine the items on the right of the equation:
499 10000 | x | = | 33 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 33 10000 | ÷ | 499 10000 |
| = | 33 10000 | × | 10000 499 |
| = | 33 | × | 1 499 |
We obtained :
| x | = | 33 499 |
Convert the result to decimal form :
| x | = | 0.066132 |
