integral of 3x^2-2x-y

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

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

Solution steps

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

\int y d x = y x

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

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

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

Add a constant to the solution

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

\int cos^{2} (r) d r

\int x^{2} \cdot a r g t h (x) d x

\int \frac{7 x ^{6}}{csc ( π + x ^{7} )} d x

\int \frac{24 x}{3 6 x ^{2} + 1} d x

\int x (3 x^{2} + 2)^{4} d x
