Transcript text: Simplify the following polynomial by combining any like terms.
\[
\begin{array}{l}
2 a b-4 a+9 a b-2 a \\
2 a b-4 a+9 a b-2 a=
\end{array}
\]
Solution
Solution Steps
To simplify the polynomial, we need to combine like terms. Like terms are terms that have the same variables raised to the same powers. In this expression, we will group and combine the terms involving \(ab\) and the terms involving \(a\).
Step 1: Combine Like Terms
We start with the polynomial expression:
\[
2ab - 4a + 9ab - 2a
\]
We can group the like terms:
\[
(2ab + 9ab) + (-4a - 2a)
\]
This simplifies to:
\[
11ab - 6a
\]
Step 2: Factor the Expression
Next, we can factor out the common term \(a\) from the expression:
\[
11ab - 6a = a(11b - 6)
\]
Final Answer
The simplified form of the polynomial is:
\[
\boxed{a(11b - 6)}
\]
