Easiet way to calculate the determinant

Question

$$A=\begin{pmatrix}4x+24 & x-12 & x-12 & x-12 & x-12\\x-12 & 4x+24 & x-12 & x-12 & x-12\\x-12 &x-12 &4x+24 & x-12 & x-12\\x-12 & x-12 & x-12 & 4x+24 & x-12\\ x-12 & x-12 & x-12 & x-12 & 4x+24\end{pmatrix}$$ Given the matrix above, what is the easiet way to calculate its determinant? I've tried getting as many zeroes on the first column for example, but I still end up with 2 non-zero elements. And it repeats for every minor, and becomes very tedious. Any help would be appreciated.
