Symbolically find a Matrix Determinant in Prime 2.0?

Is it possible in MathCAD Prime 2.0 to find the determinant of matrix that has variables in some of the matrix positions? The determinant would be a polynomial. Would this be best described as “symbolically finding the determinant of the matrix?”

Alan thank you, this is exactly what I needed!

In prime 2.0 how do I find ALL possible roots of the resultant polynomial, whatever the degree?

Use the polyroots function. Look up polyroots in Help.
