[ 1/1 Equation]
Work: Find the solution of equation x2+0.00106x+0.0000689 = 0 .
Question type: Equation
Solution:Original question:
| x | × | 2 | + | 53 50000 | x | + | 689 10000000 | = | 0 |
| Left side of the equation = | 100053 50000 | x | + | 689 10000000 |
100053 50000 | x | + | 689 10000000 | = | 0 |
Transposition :
100053 50000 | x | = | 0 | − | 689 10000000 |
Combine the items on the right of the equation:
100053 50000 | x | = | - | 689 10000000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 689 10000000 | ÷ | 100053 50000 |
| = | - | 689 10000000 | × | 50000 100053 |
| = | - | 689 200 | × | 1 100053 |
We obtained :
| x | = | - | 689 20010600 |
Convert the result to decimal form :
| x | = | - 0.000034 |
