Hello student,
Please find the answer to your question below
Given n one's implies (n-1) zero's or n(constant) implies (n-1) zero's for all constant should be in a single row or a single column
If there are 2 similar quantities in a determinant we can make one element zero by subtracting it from the other if they are in a single row or column
