integral of (5x^3+4x+3)

\int (5 x^{3} + 4 x + 3) d x

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

Solution steps

\int 5 x^{3} + 4 x + 3 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 5 x^{3} d x + \int 4 x d x + \int 3 d x

\int 5 x^{3} d x = \frac{5 x ^{4}}{4}

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

\int 3 d x = 3 x

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

Add a constant to the solution

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