integral of (4x^3-1)

Solution

\int (4 x^{3} - 1) d x

Solution

x^{4} - x + C

Solution steps

\int 4 x^{3} - 1 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 1 d x

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

\int 1 d x = x

= x^{4} - x

Add a constant to the solution

= x^{4} - x + C
