1 / | | 3 | f *(2*x - 5)*(x + 2) dx | / 0
Integral((f^3*(2*x - 5))*(x + 2), (x, 0, 1))
Rewrite the integrand:
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 integral of a constant is the constant times the variable of integration:
The result is:
Now simplify:
Add the constant of integration:
The answer is:
/ | 3 2 3 3 | 3 3 f *x 2*f *x | f *(2*x - 5)*(x + 2) dx = C - 10*x*f - ----- + ------- | 2 3 /
