integral of (-x^2+4x-3)

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

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

Solution steps

\int - x^{2} + 4 x - 3 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 4 x d x - \int 3 d x

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

\int 4 x d x = 2 x^{2}

\int 3 d x = 3 x

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

Add a constant to the solution

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

\int \frac{sec ( 2 x )}{cot ^{3} ( 2 x )} d x

\int \frac{x ^{2}}{100} d x

\int 6 x (3 x^{2} + 9)^{7} d x

\int sin^{2} (a x) cos^{2} (a x) d x

\int 2 e^{4 t} d t
