integral of x^2-10x+9

\int x^{2} - 10 x + 9 d x

\frac{x ^{3}}{3} - 5 x^{2} + 9 x + C

Solution steps

\int x^{2} - 10 x + 9 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^{2} d x - \int 10 x d x + \int 9 d x

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

\int 10 x d x = 5 x^{2}

\int 9 d x = 9 x

= \frac{x ^{3}}{3} - 5 x^{2} + 9 x

Add a constant to the solution

= \frac{x ^{3}}{3} - 5 x^{2} + 9 x + C

\int (x + 2) e^{8 x} d x

\int cos (\frac{x ^{5}}{5}) sin (\frac{x ^{5}}{5}) x^{4} d x

\int \frac{x ^{2} + 16}{3 x} d x

\int x^{2} (x^{3} + 3)^{6} d x

\int \frac{( 1 + tan ( x ) ) ^{3}}{cos ^{2} ( x )} d x
