integral of (7x^3+4x^2)

\int (7 x^{3} + 4 x^{2}) d x

\frac{7 x ^{4}}{4} + \frac{4 x ^{3}}{3} + C

Solution steps

\int 7 x^{3} + 4 x^{2} 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 7 x^{3} d x + \int 4 x^{2} d x

\int 7 x^{3} d x = \frac{7 x ^{4}}{4}

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

= \frac{7 x ^{4}}{4} + \frac{4 x ^{3}}{3}

Add a constant to the solution

= \frac{7 x ^{4}}{4} + \frac{4 x ^{3}}{3} + C
