Integrate with respect to x: ∫ x^2 e^3x dx
a. e^3x/3(x^2-2x/3)+c
b. e^3x/3 (x^2-2x/3+2/9)+c - yes* (let me know if this is correct)
c. e^3x/3 (x-2x/3+2/9)+c
d. e^3x/3 (x^2-2x/3+2/7)+c
You're absolutely right, the correct answer is b.
To find this integral you need to perform integration by partial fractions twice.
