integral of 4x+6x^2

Solution

\int 4 x + 6 x^{2} d x

Solution

2 x^{2} + 2 x^{3} + C

Solution steps

\int 4 x + 6 x^{2} 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 d x + \int 6 x^{2} d x

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

\int 6 x^{2} d x = 2 x^{3}

= 2 x^{2} + 2 x^{3}

Add a constant to the solution

= 2 x^{2} + 2 x^{3} + C
