Answer 1

Answer:

FACTORISATION

${q}^{2} - 2pq + 8pr - 4qr = 0$

$= > {q}^{2} - 4qr - 2pq + 8pr = 0$

=> q(q - 4r) - 2p(q - 4r) = 0

=> (q - 2p) × (q - 4r) = 0

=> q - 2p = 0

=> q = 2p

=> p = q/2

OR

=> q - 4r = 0

=> q = 4r

=> r = q/4

Answer 2

=> q(q - 4r) - 2p(q - 4r) = 0

=> (q - 2p) × (q - 4r) = 0

=> q - 2p = 0

=> q = 2p

=> p = q/2

OR

=> q - 4r = 0

=> q = 4r

=> r = q/4
