Tìm x: 4x^2 - 4x/2x - (1/- 1) = 0

To solve the equation 4x^2 - 4x / 2x - 1 / -1 = 0, we need to simplify the expression first.

First, let's simplify the fraction 4x^2 - 4x / 2x - 1:

4x^2 - 4x / 2x - 1 = (4x(x - 1)) / (2x - 1)

Now, let's simplify the expression further:

(4x(x - 1)) / (2x - 1) / -1 = -(4x(x - 1)) / (2x - 1)

Now, we can set the expression equal to zero:

-(4x(x - 1)) / (2x - 1) = 0

To solve for x, we can multiply both sides of the equation by (2x - 1):

-(4x(x - 1)) = 0 * (2x - 1)

Simplifying further:

-4x(x - 1) = 0

Now, we have two factors that could equal zero:

-4x = 0 or (x - 1) = 0

Solving for x in each equation:

-4x = 0
x = 0

x - 1 = 0
x = 1

Therefore, the solutions to the equation 4x^2 - 4x / 2x - 1 / -1 = 0 are x = 0 and x = 1.
