4x^2 +1/4x+2
= (4x^2 +1) / [2(2x + 1)]

2x + 1 = 0, x = -1/2

so

x CAN NOT = - 1/2

Explanation:

The given fraction is as follows.


(4x^(2)+1)/(4x+2)

It is known that rational expressions are undefined when the denomination is equal to zero.

Therefore, putting the denominator equal to zero as follows.

4x + 2 = 0

4x = -2

Solve for x as follows.

x =
(-2)/(4)

therefore, x =
(-1)/(2)

Thus, exclusion placed on the variable x for the fraction
(4x^(2)+1)/(4x+2) is
(-1)/(2).
