To solve this equation, we first need to distribute the 2x to both terms in the parentheses:

2x x - 2/5 x = 0
2x^2 - 2/5x = 0

Next, we can set the equation equal to zero and combine like terms:

2x^2 - 2/5x = 0
2x^2 = 2/5x

Now, we can isolate x by dividing both sides by x:

2x^2 / x = 2/5x / x
2x = 2/5
x = 2/5 * 1/2
x = 1/5

Therefore, the solution to the equation (2x - 2/5) * x = 0 is x = 1/5.
