Question

Perform the indicated operation. (q5 – 2q4 + q3 – q) – (2q3 + q2 + q)

Answer 1

`q^5-2q^4-q^3-q^2-2q`

Step-by-step 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:

`\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}`
