Work: Find the solution of equation 100*x*x-85*(x-25)*(x-25) = 10*83.6292*(112.73-x) .
Question type: Equation
Solution:Original question:
| 100 | x | x | − | 85 | ( | x | − | 25 | ) | ( | x | − | 25 | ) | = | 10 | × | 209073 2500 | ( | 11273 100 | − | x | ) |
| Left side of the equation = | 100 | x | x | − | 85 | x | ( | x | − | 25 | ) | + | 85 | × | 25 | ( | x | − | 25 | ) |
| = | 100 | x | x | − | 85 | x | ( | x | − | 25 | ) | + | 2125 | ( | x | − | 25 | ) |
| = | 100 | x | x | − | 85 | x | x | + | 85 | x | × | 25 | + | 2125 | ( | x | − | 25 | ) |
| = | 100 | x | x | − | 85 | x | x | + | 2125 | x | + | 2125 | ( | x | − | 25 | ) |
| = | 100 | x | x | − | 85 | x | x | + | 2125 | x | + | 2125 | x | − | 2125 | × | 25 |
| = | 100 | x | x | − | 85 | x | x | + | 2125 | x | + | 2125 | x | − | 53125 |
| = | 100 | x | x | − | 85 | x | x | + | 4250 | x | − | 53125 |
| 100 | x | x | − | 85 | x | x | + | 4250 | x | − | 53125 | = | 10 | × | 209073 2500 | ( | 11273 100 | − | x | ) |
| Right side of the equation = | 209073 250 | ( | 11273 100 | − | x | ) |
| 100 | x | x | − | 85 | x | x | + | 4250 | x | − | 53125 | = | 209073 250 | ( | 11273 100 | − | x | ) |
| Right side of the equation = | 209073 250 | × | 11273 100 | − | 209073 250 | x |
| = | 2356879929 25000 | − | 209073 250 | x |
| 100 | x | x | − | 85 | x | x | + | 4250 | x | − | 53125 | = | 2356879929 25000 | − | 209073 250 | x |
