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