Plz help me get the answer to these I need it ASAP

combine like terms
-5p^8 has the same variable and exponent as the other -5p^8
Therefore we can combine them to get
-10p^8 + 3q
No other terms are alike so that is the final answer.
Answer:
[tex]\large\boxed{-10p^8+3q}[/tex]
Step-by-step explanation:
[tex](-5p^8+3q)+(-5p^8)\qquad\text{combine like terms}\\\\=(-5p^8-5p^8)+3q\\\\=-10p^8+3q[/tex]
