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

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

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

Solution steps

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

\int \frac{x ^{2}}{2} d x = \frac{x ^{3}}{6}

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

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

Add a constant to the solution

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

\int t^{2} - 4 t - 12 d t

\int \frac{e ^{- y}}{1 + e ^{- y}} d y

\int cos (x) cos (x) cos (x) d x

\int 4 e^{x} + 4 d x

\int (x + 1) 3^{(x + 1)^{2}} d x
