Suppose that the polynomial x^2+y^2-1 is not irreducible.
It means that there exists two fractions such that :

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]
Answer:
no
Step-by-step explanation:
Original dimensions of house:
30 feet wide and 45 feet long.
Dimensions on drawing:
4 inches width and 6 inches long.
Scale is: 1 inch on drawing= 30/4 = 7. 5 ft in original.
Width of bedroom= 1.2 inches
So, actual length= 1.2 x 7.5 = 9 ft
Length of bedroom= 1.6 inches
So, actual length= 1.6 x 7.5 = 12 ft
Actual measurement of Harper's bedroom is 9 ft wide and 12 ft long.
