Work: Find the solution of equation 6.12x2+24.45x-36.27 = 0 .
Question type: Equation
Solution:Original question:
153 25 | x | × | 2 | + | 489 20 | x | − | 3627 100 | = | 0 |
| Left side of the equation = | 306 25 | x | + | 489 20 | x | − | 3627 100 |
| = | 3669 100 | x | − | 3627 100 |
3669 100 | x | − | 3627 100 | = | 0 |
Transposition :
3669 100 | x | = | 0 | + | 3627 100 |
Combine the items on the right of the equation:
3669 100 | x | = | 3627 100 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 3627 100 | ÷ | 3669 100 |
| = | 3627 100 | × | 100 3669 |
| = | 1209 | × | 1 1223 |
We obtained :
| x | = | 1209 1223 |
Convert the result to decimal form :
| x | = | 0.988553 |
