Question

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

Answer 1

Answer:

now q(p-q)+p(p-r)+r(r-p)

=qp-q^2+p^2-pr+r^2-rp

=p^2+r^2-q^2-2pr+qp

please make it brilliant answer

Answer 2

Answer:

p² + r² - q² - 2pr + pq

Step-by-step explanation:

$q(p-q)+p(p-r)+r(r-p)$

$=q(p-q)+p(p-r)-r(p-r)$

$=(p-r)^2+q(p-q)$

$=p^2-2pr+r^2+pq-q^2$

$=p^2+r^2-q^2-2pr+pq$
