Integral of x^2-4 dx
The solution
Detail solution
-
Integrate term-by-term:
-
The integral of xn is n+1xn+1 when n=−1:
∫x2dx=3x3
-
The integral of a constant is the constant times the variable of integration:
∫(−4)dx=−4x
The result is: 3x3−4x
-
Now simplify:
3x(x2−12)
-
Add the constant of integration:
3x(x2−12)+constant
The answer is:
3x(x2−12)+constant
The answer (Indefinite)
