integral of 2-sqrt(x)

\int 2 - x d x

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

Solution steps

\int 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 2 d x - \int x d x

\int 2 d x = 2 x

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

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

Add a constant to the solution

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

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

\int \frac{1}{( 1 + 9 x ^{2} ) ^{2}} d x

\int 2 x ln (x^{3}) d x

\int (5 - 4 x) sin (6 - 5 x) d x

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