Question

If `a ,b ,c` are different, then the value of `x` for which `|[0,x^2-a, x^3-b], [x^2+a,0,x^2+c ],[x^4+b, x-c,0]|=0` is
A. a
B. c
C. b
D. 0

Answer 1

Correct Answer - D
Since for x=0 the determinant reduces to the determinant of a skew -symmetric matrix of odd order which is always zero hence x=0 is the solution of the given equation.
