〖 1/1方程〗
作业:求方程 -2 = [(10000-8000)/(p2-100)]*[(100+p2)/(8000+10000) ) 的解.
题型:方程
解:原方程:| | - | 2 | = | ( | ( | 10000 | − | 8000 | ) | ÷ | ( | p | × | 2 | − | 100 | ) | ) | ( | ( | 100 | + | p | × | 2 | ) | ÷ | ( | 8000 | + | 10000 | ) | ) |
去掉方程右边的一个括号:
| | - | 2 | = | ( | 10000 | − | 8000 | ) | ÷ | ( | p | × | 2 | − | 100 | ) | × | ( | ( | 100 | + | p | × | 2 | ) | ÷ | ( | 8000 | + | 10000 | ) | ) |
| | - | 2 | ( | p | × | 2 | − | 100 | ) | = | ( | 10000 | − | 8000 | ) | ( | ( | 100 | + | p | × | 2 | ) | ÷ | ( | 8000 | + | 10000 | ) | ) |
去掉方程左边的一个括号:
| | - | 2 | p | × | 2 | + | 2 | × | 100 | = | ( | 10000 | − | 8000 | ) | ( | ( | 100 | + | p | × | 2 | ) | ÷ | ( | 8000 | + | 10000 | ) | ) |
去掉方程右边的一个括号:
| | - | 2 | p | × | 2 | + | 2 | × | 100 | = | 10000 | ( | ( | 100 | + | p | × | 2 | ) | ÷ | ( | 8000 | + | 10000 | ) | ) | − | 8000 | ( | ( | 100 | + | p | × | 2 | ) | ÷ | ( | 8000 | + | 10000 | ) | ) |
