Prove that x 2 + y2 - 1 is irreducible in q[ x, y].

weqwewe [10]

Suppose that the polynomial x^2+y^2-1 is not irreducible.
It means that there exists two fractions such that :
$(\frac{p}{q})^2+( \frac{s}{t} )^2 -1=0\\\text{rearranging the above formula we get:}\\p^2t^2=q^2(t^2-s^2)\\\text{since q and p are primes each other, we deduce that }\\\text{q divide t meaning that we can write }t=a\times t\text{ for an integer a}\\\text{rearranging again the formula and using our finding we get:}\\q^2s^2=a^2q^2(q^2-p^2)\\\text{Same argument as above, we deduce that q divide s.}$
We found that q divide t and q divide s, but s and t are supposed to be prime each other. It is a contradiction.
The polynomial x^2+y^2-1 is then irreducible in q[x,y]

If Nancy needs 3/1/4 cups of oatmeal,how many 1/4 cups of oatmeal will she use

PIT_PIT [208]

The answer is 12 1/4. how I got my answer.

Their are 4 quarters to a whole, so that means all I have to do is multiply 4×3=12, then add 1/4+12= 12 1/4.

I hope this helps!

Please help me, I will give brainliest

ipn [44]

Answer:

8w² < 4w(150-w)

Step-by-step explanation:

Square area of living : w · w = w²

Money spent : 8 · w²

Square area of artichokes : (150 - w) · w

Money earned : 4 · w · (150 - w)

Julia manages to save some money every week. That means that the money earned is bigger than the money spent ( the money spent is less than the money earned)

8 · w² < 4 · w · (150 - w)
