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