integral of 4x^2+5x

Solution

\int 4 x^{2} + 5 x d x

Solution

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

Solution steps

\int 4 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 4 x^{2} d x + \int 5 x d x

\int 4 x^{2} d x = \frac{4 x ^{3}}{3}

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

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

Add a constant to the solution

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