Question

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

Answer 1

Answer:

p^2 + q^2 +  r^2 - pq - qr - rp

Step-by-step explanation:

p (p-q) = p^2-pq

q (q-r) = q^2-qr

and

r (r-p) = r^2-rp

Therefor add them together = p^2-pq + q^2-qr +  r^2-rp

                                               = p^2 + q^2 +  r^2 - pq - qr - rp
