Try to discuss the number of solutions of the equation | x ^ 2-2x | - a = 0 about X

Let f (x) = | x ^ 2-2x|
The graph of F (x) can be drawn as follows:
Then a has two solutions on [0,1]
Then a has a solution on a = 1
Then a has two solutions on (1, positive infinity)

What is the value of some C language operations = 6 = = 9 x? The value of x = 18 < 7 & & 37 > 9 x? The value of x = 1513 > 9 x

1 x = 6 = = 9. This is very simple. Look at the priority. The priority level is basically like this: first is + + -- then is the arithmetic operator (first multiply and divide, then add and subtract), then is the relational operator, and then is the logical operator. The non operation of the logical operator ranks first, and finally is the value operator, that is, the equal sign factor

The solution equation: X × (x-1) = 39,

X × （X-1） =39
x²-x-39=0
x₁=(1-√157)/2
x₂=(1+√157)/2
