Can anyone help factor this polynomial completely?

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

The closest I've got is:

(x + 2y + 1)(x - y +2) which gives me x^2 +xy + 3x - 2y^2 + 3y + 2.

The only difference in my answer is that the second last term should be 2y not 3y.

If anyone could help that would be wonderful!!!

This year in algebra 1 we learned about quadratic and linear equations and polynomials.

What do you learn in algebra 2?

Greetings:

What is Light? Light is an EM-wave and particle.

What is an EM-wave? A wave that has an electric and magnetic component. If light is truely a binary operation (consisting of two individual physical fields) then why is it not possible to seperate each individual component into its most fundamental form? If there are physical restrictions on this process what are they?

And finally, in a philosophical sense, how can a concept rooted in experience be devoid of a temporal component? In other words, in the idea that light is an EM-wave (and particle) why is time not an essential feature of its description? As if to say, "Here it exists, but it does not relate to experience."

Please correct any conceptual mistakes made, and thanks for any well-meaning thoughts on this subject.

If not real the real Noah's Ark, then why is it there?
Out of all these discoveries, only one really matters and takes
center stage; that is the absolute "bomb" that via ELS (Bible
Code) the words "Jesus is my Name" is found clustered within the
small relevant Isaiah 53 passage:
"He was wounded for our transgressions, he was bruised for our

iniquities: the chastisement of our peace was upon him; and with

his stripes we are healed"

I've been seeing what looks like a star in the sky over the last week or so, except that sometimes it looks red. Could this be Mars? (it's not any sort of aircraft because it doesn't move.......)

For instance, if you are listening to an i-pod or talking on the phone and it got wet, could you be electrocuted? Or is that only possible if it's plugged in?
