integral of x^3-2x^2-5x+6

\int x^{3} - 2 x^{2} - 5 x + 6 d x

\frac{x ^{4}}{4} - \frac{2 x ^{3}}{3} - \frac{5 x ^{2}}{2} + 6 x + C

Solution steps

\int x^{3} - 2 x^{2} - 5 x + 6 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 x^{3} d x - \int 2 x^{2} d x - \int 5 x d x + \int 6 d x

\int x^{3} d x = \frac{x ^{4}}{4}

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

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

\int 6 d x = 6 x

= \frac{x ^{4}}{4} - \frac{2 x ^{3}}{3} - \frac{5 x ^{2}}{2} + 6 x

Add a constant to the solution

= \frac{x ^{4}}{4} - \frac{2 x ^{3}}{3} - \frac{5 x ^{2}}{2} + 6 x + C

\int cos (x) co x y - cot (x)

\int \frac{x ^{4} - 5 x}{x ^{3}} d x

\int (\frac{2}{5} x^{\frac{5}{2}} + \frac{10}{3} x^{\frac{3}{2}}) d x

\int 4 x x^{2} - 1 d x

\int \frac{11}{( x - 3 ) ( x + 8 )} d x
