Factor the polynomial completely. If the polynomial cannot be factored, write prime.
6x^2y^2 - 13xy^2 + 6y^2

y^2(x - 3)(6x - 2)
y^2(2x - 3)(3x - 2)
(3x - 3y)(2x - 2y)
(2x - 3y)(3x - 2y)

I have studied 54 credits of dentistry during 3 semesters in Ajman uni. in U.A.E. but I transfered to my country Iran for studying i a better scientific atmospher but they didnot accept me in a type 1 universities,they passage me into type 2 universities!! since they dont approve ajman and east european universities at all.now Im abit unhappy while my AGPA was (A) and I had accosiated degree in clinical laboratory sciences too.
now I have to study in persian language(mother language) and a type 2 uni!. I want to continue my education after dentistry in maxillo facial surgery and followship of cosmetic surgery.please help me.what can I do? again transfering to another country? I wanted to go to a high class of university really since most of times im grade one student.I have to pay now in my country around 8000$ per year to uni. how can I finish my education in shortest chapest and best way in best universities in dentistry then maxillofacial surgery?

Factor the polynomial completely. If the polynomial cannot be factored, write prime.
x^2 - 20x + 400

(x - 20)^2
(x + 20)^2
(x + 20)(x - 20)
prime

A starfish can grow a new arm, but you or I cannot? A salamander can regenerate a severed leg, but humans have to use manufactured prosthetic legs? The planarians (flat worms) can be cut into 50 pieces and you will end up with 50 smaller worms. If an arm of a starfish is cut off, you will have two starfish after regeneration and crickets can regenerate their legs.

These are just a few examples of creatures capable of regenerating complex structures of limbs and being able to do this repeatedly! So why do we humans not have this ability? Better phrased, what do they have that allows them to do this that we apparently do not?

I would like to get the biological / anatomical answer if you know it please. Thanks!

I've noticed that in alot of pics of space....I don't see any stars. You would think that since here on Earth you can see plenty of stars burning bright, but why in space aren't there any stars....I mean at least not in the pics. I think its a huge conspiracy by the government.

a. in each figure, name two triangles that are congruent.
b. state the reason why the triangles are congruent.(ex. S.A.S = S.A.S, S.S.S = S.S.S)
c. for each pair of triangles, name three additional pairs of parts that are congruent because they are corresponding parts of congruent triangles.

I live in Arkansas and I have a patch of these plants growing in my field. They have always been there. I am thinking that it is part of an old homestead. Or could they possibly be wild? I've never seen anything like them before.

Here are some pictures:

Reason I ask is because my local grocery has taped on their coolers that the high price of milk is because of the higher price of corn. Didnt just a couple of years ago the government force the diary industry to cut its production? Now this. Is this just another excuse to raise the price or is there merit to this claim of the price of corn being the reason?

Why is it that when a car is moving and there is a bug flying around in the car, that the bug is fine? Shouldn't it hit the back of the vehicle as soon as the car starts driving?

I have been doing a little bit of reading about this, so im in no way an expert on the subject (yet). But while looking at the equation E=mc2 I am thinking that it might not be possible to get to the speed of light. My reasoning behind this is as an object gains speed it also increases in mass. So if someone or something were to reach light speed it would reach infinite mass. Now as you gain mass you also start to generate gravity right? So if you were reach an infinite mass would you collapse under your own gravity?

We tend to consider as real the stuff to which the laws apply. For example, because we have laws for space-time, we feel that space-time is real stuff. Science does not reject subjectivity, but the laws of nature are the laws of the objective world from which somehow emerges subjectivity. In that sense, subjectivity is not real.

In this objective view of the reality, we cannot have a direct access to the laws of nature. We can only have formula and eventually build a technology to use them. However, these formula change when physics progresses. They are getting more and more accurate. The laws that are eternal are not accessible. They are part of the subjective world, a concept.

I believe that the true laws are real stuff. They are about themselves and how they get expressed in the objective world. The unification of these laws is God, eternal, everywhere, omnipotent, just like the laws. Being in the subjective world, we can experience them as God directly in our consciousness
