Work: Find the solution of equation 244.7*x-0.5*x*x*6.318-4.212*2*(1+x)-63.23*(2+x) = 0 .
Question type: Equation
Solution:Original question:
2447 10 | x | − | 1 2 | x | x | × | 3159 500 | − | 1053 250 | × | 2 | ( | 1 | + | x | ) | − | 6323 100 | ( | 2 | + | x | ) | = | 0 |
| Left side of the equation = | 2447 10 | x | − | 3159 1000 | x | x | − | 1053 125 | ( | 1 | + | x | ) | − | 6323 100 | ( | 2 | + | x | ) |
2447 10 | x | − | 3159 1000 | x | x | − | 1053 125 | ( | 1 | + | x | ) | − | 6323 100 | ( | 2 | + | x | ) | = | 0 |
| Left side of the equation = | 2447 10 | x | − | 3159 1000 | x | x | − | 1053 125 | × | 1 | − | 1053 125 | x | − | 6323 100 | ( | 2 | + | x | ) |
| = | 2447 10 | x | − | 3159 1000 | x | x | − | 1053 125 | − | 1053 125 | x | − | 6323 100 | ( | 2 | + | x | ) |
| = | 59069 250 | x | − | 3159 1000 | x | x | − | 1053 125 | − | 6323 100 | ( | 2 | + | x | ) |
| = | 59069 250 | x | − | 3159 1000 | x | x | − | 1053 125 | − | 6323 100 | × | 2 | − | 6323 100 | x |
| = | 59069 250 | x | − | 3159 1000 | x | x | − | 1053 125 | − | 6323 50 | − | 6323 100 | x |
| = | 86523 500 | x | − | 3159 1000 | x | x | − | 33721 250 |
86523 500 | x | − | 3159 1000 | x | x | − | 33721 250 | = | 0 |
