Question

If abc are root of equation find value of determinant

Answer 1

If a,b,ca,b,c are the roots of x3−px+q=0x3−px+q=0, then what is the determinant of

⎛⎝⎜abcbcacab⎞⎠⎟?(abcbcacab)?

(A) p2+6qp2+6q (B) 11 (C) pp (D) 00

In this equation given we have product of eigenvalues given as −q−q and we know product of eigenvalues is determinant then why isn't the determinant is −q−q?
