[ 1/1 Equation]
Work: Find the solution of equation 0.506 = -9.4418x2+5.6388x+0.0471 .
Question type: Equation
Solution:Original question:
253 500 | = | - | 47209 5000 | x | × | 2 | + | 14097 2500 | x | + | 471 10000 |
| Right side of the equation = | - | 47209 2500 | x | + | 14097 2500 | x | + | 471 10000 |
| = | - | 8278 625 | x | + | 471 10000 |
253 500 | = | - | 8278 625 | x | + | 471 10000 |
Transposition :
8278 625 | x | = | 471 10000 | − | 253 500 |
Combine the items on the right of the equation:
8278 625 | x | = | - | 4589 10000 |
The coefficient of the unknown number is reduced to 1 :
| x | = | - | 4589 10000 | ÷ | 8278 625 |
| = | - | 4589 10000 | × | 625 8278 |
| = | - | 4589 16 | × | 1 8278 |
We obtained :
| x | = | - | 4589 132448 |
Convert the result to decimal form :
| x | = | - 0.034648 |
