Work: Find the solution of equation (x-14.9)*(x-14.9)-767.29 = (4x-59.6)*22.3 .
Question type: Equation
Solution:Original question:
| ( | x | − | 149 10 | ) | ( | x | − | 149 10 | ) | − | 76729 100 | = | ( | 4 | x | − | 298 5 | ) | × | 223 10 |
| Left side of the equation = | x | ( | x | − | 149 10 | ) | − | 149 10 | ( | x | − | 149 10 | ) | − | 76729 100 |
| = | x | x | − | x | × | 149 10 | − | 149 10 | ( | x | − | 149 10 | ) | − | 76729 100 |
| = | x | x | − | 149 10 | x | − | 149 10 | x | + | 149 10 | × | 149 10 | − | 76729 100 |
| = | x | x | − | 149 10 | x | − | 149 10 | x | + | 22201 100 | − | 76729 100 |
| = | x | x | − | 149 5 | x | − | 13632 25 |
| x | x | − | 149 5 | x | − | 13632 25 | = | ( | 4 | x | − | 298 5 | ) | × | 223 10 |
| Right side of the equation = | 4 | x | × | 223 10 | − | 298 5 | × | 223 10 |
| = | 446 5 | x | − | 33227 25 |
| x | x | − | 149 5 | x | − | 13632 25 | = | 446 5 | x | − | 33227 25 |
The solution of the equation:
x1≈6.998095 , keep 6 decimal places
x2≈112.001905 , keep 6 decimal places
There are 2 solution(s).
