Solution

I can analyze this for you! Let me verify the steps and solution in the image.

Problem:

The integral to solve is: (3x2+4x5)dx\int (3x^2 + 4x - 5) \, dx

Steps to Solve:

  1. Break down the integral: (3x2+4x5)dx=3x2dx+4xdx5dx\int (3x^2 + 4x - 5) \, dx = \int 3x^2 \, dx + \int 4x \, dx - \int 5 \, dx

  2. Solve each term separately:

    • For 3x2dx\int 3x^2 \, dx, use the power rule: xndx=xn+1n+1\int x^n \, dx = \frac{x^{n+1}}{n+1}: 3x2dx=3x2+12+1=3x33=x3\int 3x^2 \, dx = 3 \cdot \frac{x^{2+1}}{2+1} = 3 \cdot \frac{x^3}{3} = x^3
    • For 4xdx\int 4x \, dx: 4xdx=4x1+11+1=4x22=2x2\int 4x \, dx = 4 \cdot \frac{x^{1+1}}{1+1} = 4 \cdot \frac{x^2}{2} = 2x^2
    • For 5dx\int 5 \, dx: 5dx=5x\int 5 \, dx = 5x
  3. Combine the results: (3x2+4x5)dx=x3+2x25x+C\int (3x^2 + 4x - 5) \, dx = x^3 + 2x^2 - 5x + C

Final Answer:

The correct integral is: y=x3+2x25x+Cy = x^3 + 2x^2 - 5x + C


Review of the Provided Solution:

From your image, the boxed final answer matches the correct result: y=x3+2x25x+Cy = x^3 + 2x^2 - 5x + C

This means the solution is correct.


Do you want me to explain any of the steps in more detail or clarify something specific?
