## anonymous 5 years ago Anyone want to help me with solving a determinant for a 5x5 matrix?...

1. anonymous

[a b 0 0 0],[c a b 0 0], [0 c a b 0], [0 0 c a b 0], [ 0 0 0 c a]

2. anonymous

this is making my brain hurt

3. anonymous

ha np, I think I figured out an easy way

I'll try to solve this assuming that the last 0 on the 4th row is a typing error.

5. anonymous

Ok... this might take a while. T_T

Maybe, $a\cdot(a^2-bc)\cdot(a^2-3bc)$
