integral of 15xsqrt(x)+2sqrt(x)

\int 15 x x + 2 x d x

6 x^{\frac{5}{2}} + \frac{4}{3} x^{\frac{3}{2}} + C

Solution steps

\int 15 x x + 2 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 15 x x d x + \int 2 x d x

\int 15 x x d x = 6 x^{\frac{5}{2}}

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

= 6 x^{\frac{5}{2}} + \frac{4}{3} x^{\frac{3}{2}}

Add a constant to the solution

= 6 x^{\frac{5}{2}} + \frac{4}{3} x^{\frac{3}{2}} + C

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

\int \frac{x ^{5}}{1 - x ^{2}} d x

\int \frac{7 x ^{3}}{e ^{x^{4}}} d x

\int sin^{4} (θ) cos^{3} (θ) d θ

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