Question

5. add:p(p-q),q(q-r)and r(r-p)​

Answer 1

Answer : simplifying expression:

p(p - q )

= p × p - p × q

= p^2 - p q^2

q ( q - r )

= q × q - q × r

= q^ 2 - qr

r(r - p )

=r×r×r×p

=r^2-rp

adding expressions :

p^2 - p q

+ q^ 2 - qr

+ r^ 2 - rp

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

so the answer in arrange form is;

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