integral of (3x^2+2x-1)

\int (3 x^{2} + 2 x - 1) d x

x^{3} + x^{2} - x + C

Solution steps

\int 3 x^{2} + 2 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 3 x^{2} d x + \int 2 x d x - \int 1 d x

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

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

\int 1 d x = x

= x^{3} + x^{2} - x

Add a constant to the solution

= x^{3} + x^{2} - x + C

x \to 1 + lim (x^{3})

\int \frac{1 + x ^{2}}{- 9 x} d x

\int tan^{2} (y) d y

y = \frac{1}{x ^{3}}

\int_{- 2}^{2} x^{3} - 1 d x
