Please let me know if i got this right, thanks!
Question:
∫ (x – 2/x^2)(x + 2/x^2)
Attempt at Answer:
∫ (x – 2x^2)(x + 2x^2)
∫ (x – 4x^4)
= x^3/3 – 4x^3/4
I used (x^n + 1)/(n + 1), is this correct? Thanks!
1 Answer

This line
∫ (x – 4x^4)
should say
∫ (x^2 – 4x^4)
and final result should be
x^3/3 + (4/3)x^3
Your method is correct, but be careful of details.
