I have a function defined like:

f(x) = a_1x^2+a_2x+a_3

I know that I can find its roots using Roots.jl package. How can I find its roots if its coefficients are a (3,n) matrix instead of just 3 numbers? The matrix is defined like:

\begin{bmatrix} a_{1,1} & ...& a_{1,n}\\
a_{2,1} &...& a_{2,n}\\
a_{3,1} &...& a_{3,n}\end{bmatrix}
