The value of x²+1 x²-1 d x is
Options
- A( x-1 x+1 )+c
- B( x+1 x-1 )+c
- Cx+ ( x-1 x+1 )+c
- D(x²-1 )+c
Correct answer
C. x+ ( x-1 x+1 )+c
Step-by-step solution
Let I= x²+1 x²-1 d x= x²+1-1+1 x²-1 d x aligned & I= x²-1 x²-1 d x+ 2 x²-1 d x & I= 1 d x+2 1 x²-1 d x & I=x+2 1 2 ( x-1 x+1 )+c & I=x+ ( x-1 x+1 )+c aligned
