Answer:
[tex]q^5-2q^4-q^3-q^2-2q[/tex]Explanation:
Here, we want to perform the indicated arithmetic operation
What we have to do here is to open up the parentheses and collect the like terms
Mathematically, we have that as follows:
[tex]\begin{gathered} q^5-2q^4+q^3-q-2q^3-q^2-q \\ =\text{ q}^5-2q^4+q^3-2q^3-q^2-q-q \\ =\text{ q}^5-2q^4-q^3-q^2-2q \end{gathered}[/tex]
