Solution Steps
Step 1: Identify the function
The function to integrate is \( f(x) = x^2 + 3x – 5 \)
Step 2: Apply power rule
\( \int x^2 \,dx = \frac{x^3}{3} \)
\( \int 3x \,dx = \frac{3x^2}{2} \)
\( \int -5 \,dx = -5x \)
Step 3: Combine results
\( \int (x^2 + 3x – 5) \,dx = \frac{x^3}{3} + \frac{3x^2}{2} – 5x + C \)
Example Integrals
\( \int x^2 \,dx \)
\( \int \sin(x) \,dx \)
\( \int e^x \,dx \)
\( \int \frac{1}{x} \,dx \)
\( \int \cos(2x) \,dx \)
\( \int x e^x \,dx \)
