(x-a)(x+3a).

Answer 1

You have asked a similar question before. Review the solution given to you then and you'll be able to find the answer.

Answer 2

Assuming you mean finding the determinant.

Answer 3

u can not solve this question?

Answer 4

Actually I can :-D but I'm not giving you the answer because you have asked the exact same question only with different elements of the matrix.

Answer 5

But it had the same form.

Answer 6

ok as u wish!
