**M= |3-2x^3_____-4+2x^2+4x^3______0|**

|-x^3________1+x^2+2x^3_______0|

|-8-6x^2_____16+12x^2____-1-3x^2|

find the determinant.

* I put the underscores for spacing.

## The Attempt at a Solution

I first tried finding det(A) as if it was a regular matrix of numbers, but that doesn't seem to work. So I'm really not sure how to find the determinant for a matrix of polynomial equations. Where would you actually start?
