To solve the quadratic equation \( \frac{1}{4}x^2 + 2x + 4 = 0 \), we can start by multiplying the entire equation by 4 to eliminate the fraction:

\[
4 \left( \frac{1}{4}x^2 \right) + 4(2x) + 4(4) = 0
\]

This simplifies to:

\[
x^2 + 8x + 16 = 0
\]

Next, we can factor the quadratic equation. We are looking for two numbers that multiply to 16 and add to 8. The numbers 4 and 4 fit this requirement. Thus, we can factor the equation as follows:

\[
(x + 4)(x + 4) = 0
\]

This can also be written as:

\[
(x + 4)^2 = 0
\]

To find the solution, we set the factor equal to zero:

\[
x + 4 = 0
\]

Solving for \(x\), we get:

\[
x = -4
\]

Since the equation \( (x + 4)^2 = 0 \) has only one unique solution (a double root), the solution to the original quadratic equation is:

\[
\boxed{-4}
\]
