Work: Find the solution of equation 50% = -30.019x2+56.518+24.998 .
Question type: Equation
Solution:Original question:
50 100 | = | - | 30019 1000 | x | × | 2 | + | 28259 500 | + | 12499 500 |
| Right side of the equation = | - | 30019 500 | x | + | 28259 500 | + | 12499 500 |
| = | - | 30019 500 | x | + | 20379 250 |
50 100 | = | - | 30019 500 | x | + | 20379 250 |
Transposition :
30019 500 | x | = | 20379 250 | − | 50 100 |
Combine the items on the right of the equation:
30019 500 | x | = | 10127 125 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 10127 125 | ÷ | 30019 500 |
| = | 10127 125 | × | 500 30019 |
| = | 10127 | × | 4 30019 |
We obtained :
| x | = | 40508 30019 |
Convert the result to decimal form :
| x | = | 1.349412 |
