integral of (x+6)(x-4)

\int (x + 6) (x - 4) d x

\frac{x ^{3}}{3} + x^{2} - 24 x + C

Solution steps

\int (x + 6) (x - 4) d x

Expand

(x + 6) (x - 4) : x^{2} + 2 x - 24

= \int x^{2} + 2 x - 24 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^{2} d x + \int 2 x d x - \int 24 d x

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

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

\int 24 d x = 24 x

= \frac{x ^{3}}{3} + x^{2} - 24 x

Add a constant to the solution

= \frac{x ^{3}}{3} + x^{2} - 24 x + C
