integral of 3x^2-5x

Solution

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

Solution

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

Solution steps

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

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

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

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

Add a constant to the solution

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