integral of 1-4x^2

Solution

\int 1 - 4 x^{2} d x

Solution

x - \frac{4 x ^{3}}{3} + C

Solution steps

\int 1 - 4 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 1 d x - \int 4 x^{2} d x

\int 1 d x = x

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

= x - \frac{4 x ^{3}}{3}

Add a constant to the solution

= x - \frac{4 x ^{3}}{3} + C
