integral of 6x^2-5x-1

\int 6 x^{2} - 5 x - 1 d x

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

Solution steps

\int 6 x^{2} - 5 x - 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 6 x^{2} d x - \int 5 x d x - \int 1 d x

\int 6 x^{2} d x = 2 x^{3}

\int 5 x d x = \frac{5 x ^{2}}{2}

\int 1 d x = x

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

Add a constant to the solution

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