Solution
Solution Steps
To find the indefinite integral of the polynomial \( \int (2x^3 + 5x^2 - 3x + 2) \, dx \), we will integrate each term separately. The power rule for integration states that the integral of \( x^n \) is \( \frac{x^{n+1}}{n+1} \). We apply this rule to each term of the polynomial and add a constant of integration \( C \).
Step 1: Define the Integral
We need to find the indefinite integral of the polynomial \( \int (2x^3 + 5x^2 - 3x + 2) \, dx \).
Step 2: Apply the Power Rule
Using the power rule for integration, we integrate each term separately:
For \( 2x^3 \), the integral is \( \frac{2}{4} x^4 = \frac{1}{2} x^4 \).
For \( 5x^2 \), the integral is \( \frac{5}{3} x^3 \).
For \( -3x \), the integral is \( -\frac{3}{2} x^2 \).
For \( 2 \), the integral is \( 2x \).
Step 3: Combine the Results
Combining all the results, we have:
\[
\int (2x^3 + 5x^2 - 3x + 2) \, dx = \frac{1}{2} x^4 + \frac{5}{3} x^3 - \frac{3}{2} x^2 + 2x + C
\]
Final Answer
The final result of the indefinite integral is:
\[
\boxed{\frac{1}{2} x^4 + \frac{5}{3} x^3 - \frac{3}{2} x^2 + 2x + C}
\]
