Solution

Why ? No one can solve this 22 . If someone should solve , plz tell me .

positive integers which give result 10 after sum

(1, 1, 8) = 3 solutions

(1, 2, 7) = 6 solutions

(1, 3 , 6) = 6 solutions

(1, 4 , 5) = 6 solutions

(2, 2, 6) = 3 solutions

(2, 3, 5) = 6 solutions

(2, 4, 4) = 3 solutions

(3, 3, 4) = 3 solutions

total = 36

Try if you want

(p² + q² + r² - pq - qr - rp) / (p + q + r) = z

q = n

Put

1/n = z

z is integer

So n = 1 or - 1
