To perform the long division of the polynomial \(33x^5 + 22x^4 - 50x^3 - 26x^2 + 13x\) by \(3x^2 + 2x - 1\), we will follow the long division steps for polynomials.
### Step 1: Set Up the Division
We write the dividend \(33x^5 + 22x^4 - 50x^3 - 26x^2 + 13x\) and the divisor \(3x^2 + 2x - 1\).
### Step 2: Divide the Leading Terms
1. **Divide the leading term of the dividend by the leading term of the divisor**:
\[
\frac{33x^5}{3x^2} = 11x^3
\]
2. **Multiply the entire divisor by \(11x^3\)**:
\[
11x^3(3x^2 + 2x - 1) = 33x^5 + 22x^4 - 11x^3
\]
3. **Subtract this from the original polynomial**:
\[
(33x^5 + 22x^4 - 50x^3 - 26x^2 + 13x) - (33x^5 + 22x^4 - 11x^3) = -50x^3 + 11x^3 - 26x^2 + 13x
\]
This simplifies to:
\[
-39x^3 - 26x^2 + 13x
\]
### Step 3: Repeat the Process
1. **Divide the leading term of the new polynomial by the leading term of the divisor**:
\[
\frac{-39x^3}{3x^2} = -13x
\]
2. **Multiply the entire divisor by \(-13x\)**:
\[
-13x(3x^2 + 2x - 1) = -39x^3 - 26x^2 + 13x
\]
3. **Subtract from the new polynomial**:
\[
(-39x^3 - 26x^2 + 13x) - (-39x^3 - 26x^2 + 13x) = 0
\]
### Conclusion of Long Division
After the subtraction, we find that there are no remaining terms. Thus, all terms have canceled out.
### Result
The quotient when dividing \(33x^5 + 22x^4 - 50x^3 - 26x^2 + 13x\) by \(3x^2 + 2x - 1\) is:
\[
**11x^3 - 13x**
\]
The final answer is:
\[
\boxed{11x^3 - 13x}
\]
