[ 1/1 Equation]
Work: Find the solution of equation x(60-x) = 864 .
Question type: Equation
Solution:Original question:
| x | ( | 60 | − | x | ) | = | 864 |
| Left side of the equation = | x | × | 60 | − | x | x |
| 60 | x | − | x | x | = | 864 |
After the equation is converted into a general formula, it is converted into:
( x - 24 )( x - 36 )=0
From
x - 24 = 0
x - 36 = 0
it is concluded that:：
x1=24
x2=36
There are 2 solution(s).
