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]

Solve the equation
Umnica [9.8K]
3/4x + 3 - 2x = -1/4 + 1/2x + 5

Put in terms of 4 as denominator
3/4x + 12/4 - 8/4x = -1/4 + 2/4x + 20/4

Combine like terms
-5/4x + 12/4 = 2/4x + 19/4

Simplify
12/4 = 7/4x + 19/4
-7/4 = 7/4x
x = -1 :)

Check:
3/4(-1) + 3 - 2(-1) = -1/4 + 1/2(-1) + 5
-3/4 + 3 + 2 = -1/4 - 1/2 + 5
-3/4 + 5 = -3/4 + 5
-3/4 = -3/4 :)
