The integral of a constant is equal to the constant times the integral's variable
$n\left(1-2n\right)^3$
2
As the integral that we are solving is an indefinite integral, when we finish integrating we must add the constant of integration $C$
$x^2\sin\left(x^2+4\right)+C_0$
Final Answer
$x^2\sin\left(x^2+4\right)+C_0$
