Question

p(p – q) + q(q – r) + r(r – p) pls solve this.. will mark the person brainliest for the first and correct answer with perfect explaination

Answer 1

Step-by-step explanation:

p²-pq+q²-rq +r² - rp

= p²+q²+r² -pq -qr-rp

= (p³+q³+r³ - 3pqr) ÷ (p+q+r)

Answer 2

$\huge{\underline{\underline{\boxed{\sf{\purple{Answer}}}}}}$

p(p – q) + q(q – r) + r(r – p)

= p² - pq - q² - qr + r² - pr

= p² - q² + r² - pq - qr - pr
