Question:: Sir 
I read in one of the arihant books a note which I was not able to understand which is as follows:-

THERE IS A GOLDEN RULE IN DETERMINANT THAT 
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

So Please tell me the meaning of this line in an understandable and simple language accompanied by an illustrative example.

										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
