Evaluate the following indefinite integrals:

$\int{(5x^2-6x+3)}dx$

Thanks for any help!

Thanks for any help!

$\int ax^{n} dx = \frac{ax^{n+1}}{n+1} + C$

That's all you need to know for this.

$\int{(5x^2-6x+3)}dx$
$5\int{x^2dx}-(6\int{xdx})+(3\int{dx})$
$5(\frac{x^3}{3})-6(\frac{x^2}{2})+3x+c$
$\frac{5}{3}x^3-3x^2+3x+c$
