Work: Find the solution of equation 0.168x = 0.12x+0.05*0.12(x-1)x/2 .
Question type: Equation
Solution:Original question:
21 125 | x | = | 3 25 | x | + | 1 20 | × | 3 25 | ( | x | − | 1 | ) | x | ÷ | 2 |
| Right side of the equation = | 3 25 | x | + | 3 1000 | ( | x | − | 1 | ) | x |
21 125 | x | = | 3 25 | x | + | 3 1000 | ( | x | − | 1 | ) | x |
| Right side of the equation = | 3 25 | x | + | 3 1000 | x | x | − | 3 1000 | × | 1 | x |
| = | 3 25 | x | + | 3 1000 | x | x | − | 3 1000 | x |
| = | 117 1000 | x | + | 3 1000 | x | x |
21 125 | x | = | 117 1000 | x | + | 3 1000 | x | x |
After the equation is converted into a general formula, it is converted into:
( x +0 )( x - 17 )=0
From
x + 0 = 0
x - 17 = 0
it is concluded that:：
x1=0
x2=17
