integral of (9x^2-5x+3)

\int (9 x^{2} - 5 x + 3) d x

3 x^{3} - \frac{5 x ^{2}}{2} + 3 x + C

Solution steps

\int 9 x^{2} - 5 x + 3 d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 9 x^{2} d x - \int 5 x d x + \int 3 d x

\int 9 x^{2} d x = 3 x^{3}

\int 5 x d x = \frac{5 x ^{2}}{2}

\int 3 d x = 3 x

= 3 x^{3} - \frac{5 x ^{2}}{2} + 3 x

Add a constant to the solution

= 3 x^{3} - \frac{5 x ^{2}}{2} + 3 x + C

x \to 2 lim ((x - 2)^{x - 2})

\frac{d}{d x} ((\frac{1}{2 x + 3})^{3})

f (x) = arctan (\frac{1 + x}{1 - x})

\frac{\partial}{\partial x} (1 + x^{3} + y^{4})

\int \frac{3 x + 4}{x + 3} d x
