x^2+4 x^4+16 d x is equal to
Options
- A1 2 2 ⁻¹ ( x^2+4 2 x )+c
- B1 2 2 ⁻¹ ( x^2-4 2 2 x )+c
- C1 2 2 ⁻¹ ( x^2+4 2 2 x )+c
- D1 2 ⁻¹ ( x^2-4 2 x )+c
Correct answer
B. 1 2 2 ⁻¹ ( x^2-4 2 2 x )+c
Step-by-step solution
x^2+4 x^4+16 d x= 1+ 4 x^2 x^2+ 16 x^2 d x= d (x- 4 x ) (x- 4 x )^2+8 = d t t^2+(2 2 )^2 , where t=x- 4 x = 1 2 2 ⁻¹ ( x^2-4 2 2 x )+c
