# Can 2xy - y - 1 be factored out? How?

about all you can do is take the common y out of the first two terms; that in itself is not much help.

dont know if this is rite or not..but just a guess..

assuming

2xy - y - 1 = 0

2xy - y = 1

y(2x-1)= 1

fingers crossed...hopefully thts rite!

## To factor the expression 2xy - y - 1, you can first notice that there is a common factor of y in the first two terms. You can factor out y from these terms, which gives you:

y(2x - 1) - 1

However, this is as far as you can go with factoring this expression. The remaining expression, (2x - 1) - 1, cannot be factored further. Therefore, the factored form of 2xy - y - 1 is y(2x - 1) - 1.
