integral of (3x^2+(25)/(2x^3))

\int (3 x^{2} + \frac{25}{2 x ^{3}}) d x

x^{3} - \frac{25}{4 x ^{2}} + C

Solution steps

\int 3 x^{2} + \frac{25}{2 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 3 x^{2} d x + \int \frac{25}{2 x ^{3}} d x

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

\int \frac{25}{2 x ^{3}} d x = - \frac{25}{4 x ^{2}}

= x^{3} - \frac{25}{4 x ^{2}}

Add a constant to the solution

= x^{3} - \frac{25}{4 x ^{2}} + C

\int (4 w - 3)^{3} d w

\int \frac{10 ln ( x )}{x} d x

\int (13 - x) x d x

\int (y + 2) (y - 1) d y

\int \frac{x + 1}{( x - 1 ) ( x - 2 )} d x
