integral of x^2+a^2

Solution

\int x^{2} + a^{2} d x

Solution

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

Solution steps

\int x^{2} + a^{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 x^{2} d x + \int a^{2} d x

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

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

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

Add a constant to the solution

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