integral of (2x^2+3x+1)

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

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

Solution steps

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

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

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

\int 1 d x = x

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

Add a constant to the solution

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

\int 2 u^{- 1} d u

\int \frac{2}{x 36 + x ^{2}} d x

\int \frac{7 x - 23}{( x - 2 ) ( x - 5 )} d x

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

\int \frac{6 x ^{2} - 32 x + 41}{x - 4} d x
