integral of (9x^2-10)/((3x^3-10x)^4)

\int \frac{9 x ^{2} - 10}{( 3 x ^{3} - 10 x ) ^{4}} d x

- \frac{1}{3 ( 3 x ^{3} - 10 x ) ^{3}} + C

Solution steps

\int \frac{9 x ^{2} - 10}{( 3 x ^{3} - 10 x ) ^{4}} d x

Apply u-substitution

: \int \frac{1}{u ^{4}} d u

= \int \frac{1}{u ^{4}} d u

Apply the Power Rule

: - \frac{1}{3 u ^{3}}

= - \frac{1}{3 u ^{3}}

Substitute back

u = 3 x^{3} - 10 x

= - \frac{1}{3 ( 3 x ^{3} - 10 x ) ^{3}}

Add a constant to the solution

= - \frac{1}{3 ( 3 x ^{3} - 10 x ) ^{3}} + C

\int 3 t^{2} t^{3} + 2 d t

\int \frac{π}{x ^{2} + 16} d x

\int \frac{4 x ^{2} + x + 1}{x ^{3} - 1} d x

\int \frac{1}{x - 18} d x

\int (8 x^{3} + 4 x) (x^{4} + x^{2})^{\frac{5}{2}} d x
