integral of x^2+4x-5

Solution

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

Solution

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

Solution steps

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

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

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

\int 5 d x = 5 x

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

Add a constant to the solution

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