Question

factor.
x^2-3xy+2y^2

Answer 1

not too many choices if it is going to factor are there?

Answer 2

that didn't really make sense?...sorry

Answer 3

first terms have to be \(x\) and last term can be either \(2y\) and \(y\) or \(-2y\) and \(-y\)

Answer 4

since the product of the first terms must be \(x^2\) and the product of the last terms has to be \(2y^2\) so your only choices are
\[(x+2y)(x+y)\] or
\[(x-2y)(x-y)\] that is it. then check to see which one is right, i.e. which one gives you
\[x^2-3xy+y^2\] when you multiply out
