[ 1/1 Equation]
Work: Find the solution of equation x(24-2x) = 72 .
Question type: Equation
Solution:Original question:
Remove the bracket on the left of the equation:
The equation is transformed into :
After the equation is converted into a general formula, it is converted into:
( x - 6 )( x - 6 )=0
From
x - 6 = 0
x - 6 = 0
it is concluded that:：

☆1 equations
[ 1/1 Equation]
Work: Find the solution of equation x(24-2x) = 72 .
Question type: Equation
Solution:Original question:
| x | ( | 24 | − | 2 | x | ) | = | 72 |
| Left side of the equation = | x | × | 24 | − | x | × | 2 | x |
| 24 | x | − | x | × | 2 | x | = | 72 |
After the equation is converted into a general formula, it is converted into:
( x - 6 )( x - 6 )=0
From
x - 6 = 0
x - 6 = 0
it is concluded that:：
x1=6
x2=6
There are 2 solution(s).
