How would you factor:can you guys help me factor this polynomial.
by the way this is what i tried in prob 1
$2(x-y)^2+5(x-y)-3$ -->> i'm stuck here. and in prob 2 i have no idea where and how to start.
Consider the expansion of:is that always the form we get when we multiply trinomials?
can you give me a more generalized form.
