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

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

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

Solution steps

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

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

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

\int 1 d x = x

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

Add a constant to the solution

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