Answer: x = 2

Step-by-step explanation: Since we are looking for the values of x for which the denominator is equal to zero , we will equate the denominator to zero , that is :

[tex]x^{2}[/tex] - 4x + 4 = 0

Factorising , we have

(x - 2 ) ( x - 2 ) = 0

that is ,

x - 2 = 0 or x - 2 = 0

Therefore :

x = 2 twice
