1 / | | 3 | x *(2*x - 1) dx | / 0
Integral(x^3*(2*x - 1), (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 result is:
Now simplify:
Add the constant of integration:
The answer is:
/ | 4 5 | 3 x 2*x | x *(2*x - 1) dx = C - -- + ---- | 4 5 /
