Question

Subtract 4p?q – 3pq + 5pq? – 8p + 77 - 10 from
18 – 3p – 119 + 5pq - 2pq? + 5p?q​

Answer 1

Step-by-step explanation:

18 – 3p – 119 + 5pq - 2pq² + 5p²q - (4p²q – 3pq + 5pq² – 8p + 77 - 10)

= 18 – 3p – 119 + 5pq - 2pq² + 5p²q - 4p²q + 3pq - 5pq² + 8p - 77 + 10

= (18-119-77+10) + (-3p+8p) + (5pq+3pq) + (-2pq²-5pq²) + (5p²q-4p²q)

= (-168) + (5p) + (8pq) + (-7pq²) + (1p²q)

= -168 + 5p + 8pq - 7pq² + p²q
