integral of 12x^3-6x^2+4/x

\int 12 x^{3} - 6 x^{2} + \frac{4}{x} d x

3 x^{4} - 2 x^{3} + 4 ln ∣ x ∣ + C

Solution steps

\int 12 x^{3} - 6 x^{2} + \frac{4}{x} 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 12 x^{3} d x - \int 6 x^{2} d x + \int \frac{4}{x} d x

\int 12 x^{3} d x = 3 x^{4}

\int 6 x^{2} d x = 2 x^{3}

\int \frac{4}{x} d x = 4 ln ∣ x ∣

= 3 x^{4} - 2 x^{3} + 4 ln ∣ x ∣

Add a constant to the solution

= 3 x^{4} - 2 x^{3} + 4 ln ∣ x ∣ + C

\int 6 \cdot 2^{- x} - 3 d x

\int \frac{y}{e ^{y^{2}}} d y

\int (3 x^{3} - 5 x^{2} + 4) d x

\int \frac{1 - 3 x}{2 x - 3 x ^{2}} d x

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