Add: p ( p - q), q ( q - r) and r ( r - p)

Answer: p2 + q2 + r2 – pq – qr – pr

p(p – q), q(q – r) and r(r – p)

p( p – q) + q(q – r) + r( r – p)

= (p2 – pq) + (q2 – qr) + (r2 – pr)

= p2 – pq + q2 – qr + r2 – pr

= p2 + q2 + r2 – pq – qr – pr

p( p – q) + q(q – r) + r( r – p) = p2 + q2 + r2 – pq – qr – pr
