Hi, I am using sage-4.5.1.
I need to symbolically find the determinant of a 4 X 4 matrix. So i do something like: sage: mat = [ [-,-,-,-],[-,-,-,-],[-,-,-,-],[-,-,-,-] ] sage: A = matrix(mat) sage: solve(det(A)==0,c) Here c is one of the given algebraic quantities. The solution has been provided in a book as: c^2 = p - q, where p & q are again some algebraic quantities. But sage gives it as c = some algebraic quantity with no square-root sign. So you can see that this removes the possibility of getting comples solutions for c. Even assuming that p > q the answer computed appears different. What am i doing wrong?
