integral of (2sqrt(x)-9)

\int (2 x - 9) d x

\frac{4}{3} x^{\frac{3}{2}} - 9 x + C

Solution steps

\int 2 x - 9 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 2 x d x - \int 9 d x

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

\int 9 d x = 9 x

= \frac{4}{3} x^{\frac{3}{2}} - 9 x

Add a constant to the solution

= \frac{4}{3} x^{\frac{3}{2}} - 9 x + C

\int csc^{2} (x) cos (x) d x

\int x^{4} (x^{5} + 3)^{104} d x

\int \frac{x ^{2} - 5}{2 x ^{3}} d x

\int ln (4 x^{2} + 1) d x

\int e^{100 x} d x
