[ 1/1 Equation]
Work: Find the solution of equation (-x2/50)+10x-300 = 0 .
Question type: Equation
Solution:Original question:
| ( | - | x | × | 2 | ÷ | 50 | ) | + | 10 | x | − | 300 | = | 0 |
| Left side of the equation = | - | x | × | 2 | ÷ | 50 | + | 10 | x | − | 300 |
| = | - | x | × | 1 25 | + | 10 | x | − | 300 |
| = | 249 25 | x | − | 300 |
249 25 | x | − | 300 | = | 0 |
Transposition :
249 25 | x | = | 0 | + | 300 |
Combine the items on the right of the equation:
249 25 | x | = | 300 |
The coefficient of the unknown number is reduced to 1 :
| x | = | 300 | ÷ | 249 25 |
| = | 300 | × | 25 249 |
| = | 100 | × | 25 83 |
We obtained :
| x | = | 2500 83 |
Convert the result to decimal form :
| x | = | 30.120482 |
