5 (x^6+1 ) x^2+1 ~d x= (Where C is a constant of integration.)
Options
- A5 (x^7+1 )+ (x^2+1 )+C
- Bx^5- 5 x^3 3 +5 x+C
- C5 x^7 7 +5 x+5 ⁻¹ x+C
- D5 ⁻¹ x+ (x^2+1 )+C
Correct answer
B. x^5- 5 x^3 3 +5 x+C
Step-by-step solution
aligned & 5 (x^6+1 ) x^2+1 ~d x= 5 (x^2+1 ) (x^4-x^2+1 ) x^2+1 ~d x & =5 (x^4-x^2+1 ) d x & =5 x^5 5 - x^3 3 +x +C & =x^5- 5 3 x^3+5 x+C aligned
