Math Problem Statement

integral (3x2+8x−2) dx

Solution

The given integral is:

(3x2+8x2)dx\int (3x^2 + 8x - 2) \, dx

To solve this, we apply the power rule of integration, which states that:

xndx=xn+1n+1+C\int x^n \, dx = \frac{x^{n+1}}{n+1} + C

Now, integrate each term separately:

  1. 3x2dx=3x33=x3\int 3x^2 \, dx = 3 \cdot \frac{x^3}{3} = x^3
  2. 8xdx=8x22=4x2\int 8x \, dx = 8 \cdot \frac{x^2}{2} = 4x^2
  3. (2)dx=2x\int (-2) \, dx = -2x

Now, putting it all together:

x3+4x22x+Cx^3 + 4x^2 - 2x + C

where CC is the constant of integration.

Thus, the solution is:

x3+4x22x+Cx^3 + 4x^2 - 2x + C
