Integrate the function f(x) = 6x4 - 9x2 - √𝑥 (

To integrate the function \( f(x) = 6x^4 - 9x^2 - \sqrt{x} \), we can handle each term separately. Let's compute the integral step by step.

### 1. Integral of \( 6x^4 \):

\[
\int 6x^4 \, dx = 6 \cdot \frac{x^5}{5} = \frac{6x^5}{5}
\]

### 2. Integral of \( -9x^2 \):

\[
\int -9x^2 \, dx = -9 \cdot \frac{x^3}{3} = -3x^3
\]

### 3. Integral of \( -\sqrt{x} \):

We rewrite \( \sqrt{x} \) as \( x^{1/2} \), then integrate:

\[
\int -x^{1/2} \, dx = - \frac{x^{3/2}}{3/2} = -\frac{2}{3}x^{3/2}
\]

### Putting it all together:

The indefinite integral of \( f(x) = 6x^4 - 9x^2 - \sqrt{x} \) is:

\[
\int (6x^4 - 9x^2 - \sqrt{x}) \, dx = \frac{6x^5}{5} - 3x^3 - \frac{2}{3}x^{3/2} + C
\]

where \( C \) is the constant of integration.

### Final Answer:

\[
\boxed{\int f(x) \, dx = \frac{6x^5}{5} - 3x^3 - \frac{2}{3}x^{3/2} + C}
\]
