Understand the problem

Solve the following equation:

x24x+4=0 x^2-4x+4=0

2

Step-by-step solution

The given equation is:

x24x+4=0 x^2 - 4x + 4 = 0

This resembles a perfect square trinomial. The expression x24x+4 x^2 - 4x + 4 can be rewritten as (x2)2 (x-2)^2 . This can be verified by expanding (x2)(x2) (x-2)(x-2) to confirm it equals x24x+4 x^2 - 4x + 4 .

Therefore, the equation becomes:

(x2)2=0 (x-2)^2 = 0

To solve for x x , take the square root of both sides:

x2=0 x - 2 = 0

Adding 2 to both sides gives:

x=2 x = 2

Thus, the solution to the equation x24x+4=0 x^2 - 4x + 4 = 0 is x=2 x = 2 , which corresponds to the unique real root of the equation.
