Work: Find the solution of equation 0 = 1.1353x2-2.3928x+1.2421 .
Question type: Equation
Solution:Original question:
| 0 | = | 11353 10000 | x | × | 2 | − | 2991 1250 | x | + | 12421 10000 |
| Right side of the equation = | 11353 5000 | x | − | 2991 1250 | x | + | 12421 10000 |
| = | - | 611 5000 | x | + | 12421 10000 |
| 0 | = | - | 611 5000 | x | + | 12421 10000 |
Transposition :
611 5000 | x | = | 12421 10000 | − | 0 |
Combine the items on the right of the equation:
611 5000 | x | = | 12421 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 12421 10000 | ÷ | 611 5000 |
| = | 12421 10000 | × | 5000 611 |
| = | 12421 2 | × | 1 611 |
We obtained :
| x | = | 12421 1222 |
Convert the result to decimal form :
| x | = | 10.164484 |
