Add:
2p4 – 3p3 + p2 – 5p + 7, –3p4 – 7p3 – 3p2 – p – 12
उत्तर
We have,
(2p4 – 3p3 + p2 – 5p + 7) + (–3p4 – 7p3 – 3p2 – p – 12)
= 2p4 – 3p3 + p2 – 5p + 7 – 3p4 – 7p3 – 3p2 – p – 12
= (2p4 – 3p4) + (–3p3 – 7p3) + (p2 – 3p2) + (–5p – p) + (7 – 12) ...[Grouping like terms]
= – p4 + (–10p3) + (–2p2) + (–6p) + (–5)
= – p4 – 10p3 – 2p2 – 6p – 5
