Answer:
2p4 - 1p2 + 9p3 + 8p
Step-by-step explanation:
Combine like terms based on the exponent value of "p" for example p^4 can only be added with another p^4
Answer: [tex]2p^{4} + 9px^{3} -p^{2}+ 8p[/tex]
[tex](2p^{4} - 6p^{2} + 6px^{3}) + (8p +3p^{3} + 5p^{2} )\\2p^{4} - 6p^{2} + 6px^{3} + 8p +3p^{3} + 5p^{2} \\2p^{4} + 6px^{3} + 3p^{3} + 5p^{2} - 6p^{2} + 8p \\2p^{4} + 9px^{3} -p^{2}+ 8p[/tex]
