b / | | / 2 \ | \a*x + b*x/ dx | / 0
Integral(a*x^2 + b*x, (x, 0, b))
Integrate term-by-term:
The integral of a constant times a function is the constant times the integral of the function:
The integral of is when :
So, the result is:
The integral of a constant times a function is the constant times the integral of the function:
The integral of is when :
So, the result is:
The result is:
Now simplify:
Add the constant of integration:
The answer is:
/ | 2 3 | / 2 \ b*x a*x | \a*x + b*x/ dx = C + ---- + ---- | 2 3 /
