Question

then n equals

 

 

Solution

Correct option is

– 1

The degree of the determinant is n + (n + 2) + (n + 3) = 3n + 5 and the degree of the expression on RHS is 2.

{Equating degree alone does not sufficient to evaluate n, the determinant might not be equal however since all options have values we conclude for n= – 1.}
