integral of (4x^3+5x^2-7x)

\int (4 x^{3} + 5 x^{2} - 7 x) d x

x^{4} + \frac{5 x ^{3}}{3} - \frac{7 x ^{2}}{2} + C

Solution steps

\int 4 x^{3} + 5 x^{2} - 7 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 4 x^{3} d x + \int 5 x^{2} d x - \int 7 x d x

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

\int 5 x^{2} d x = \frac{5 x ^{3}}{3}

\int 7 x d x = \frac{7 x ^{2}}{2}

= x^{4} + \frac{5 x ^{3}}{3} - \frac{7 x ^{2}}{2}

Add a constant to the solution

= x^{4} + \frac{5 x ^{3}}{3} - \frac{7 x ^{2}}{2} + C
