Find the complex roots of the following quadratic equation.
\[ 4x^2 + 0.0025 = 0 \]
\( x_1=-\frac1{40}\mathrm{i}\text{, } x_2=\frac1{40}\mathrm{i} \)
\( x_1=-\frac1{4}\mathrm{i}\text{, } x_2=\frac1{4}\mathrm{i} \)
\( x_1=-\frac5{16}\mathrm{i}\text{, } x_2=\frac5{16}\mathrm{i} \)
\( x_1=-\frac5{4}\mathrm{i}\text{, } x_2=\frac5{4}\mathrm{i} \)
