integral of (3x^2-a)

Solution

\int (3 x^{2} - a) d x

Solution

x^{3} - a x + C

Solution steps

\int 3 x^{2} - a 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 3 x^{2} d x - \int a d x

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

\int a d x = a x

= x^{3} - a x

Add a constant to the solution

= x^{3} - a x + C
