Answer 1

Solution:-

(6p-5q+5r)(-2p-7q+8r)

=> 6p(-2p-7q+8r) -5q(-2p-7q+8r)+5r(-2p-7q+8r)

=> -12p²-42pq+48pr+10pq+35q²-40qr-10pr-35qr+40r²

=> -12p²-32pq+38pr+35q²-75qr+40r²

=> -12p²+35q²+40r²-32pq+38pr-75qr

Hope it helps you

$(6p - 5q + 5r)( - 2p - 7q + 8r)$

$= - 12 {p}^{2} - 42pq + 48pr + 10pq + 35 {q}^{2} - 40qr - 10pr - 35qr + 40 {r}^{2}$

$= - 12 {p}^{2} + 35 {q}^{2} + 40 {r}^{2} - 32pq - 75qr + 38pr$
