Answer 2

Answer:

Question :-

Subtract -2p3+4p2-7 -p from 16 –8p.

Required Answer :-

$= {2p}^{3} - {4p}^{2} - 7p+23$

Solution :-

$16-8p-( - {2p}^{3} +{4p}^{2} \:-7 -p)$

$= 16 - 8p + {2p}^{3} - {4p}^{2} + 7 + p$

$= 16 + 7 - 8p + p + {2p}^{3} - {4p}^{2}$

$= 23 - 7p + {2p}^{3} - {4p}^{2}$

$= {2p}^{3} - {4p}^{2} - 7p+23$
