integral of (9x^2-7)

Solution

\int (9 x^{2} - 7) d x

Solution

3 x^{3} - 7 x + C

Solution steps

\int 9 x^{2} - 7 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 9 x^{2} d x - \int 7 d x

\int 9 x^{2} d x = 3 x^{3}

\int 7 d x = 7 x

= 3 x^{3} - 7 x

Add a constant to the solution

= 3 x^{3} - 7 x + C
