If ⁻¹(x+2)+ ⁻¹(x-2)- ⁻¹ ( 1 2 )=0 , then one value of x is
Options
- A-1
- B1 2
- C1
- D2
Correct answer
C. 1
Step-by-step solution
aligned & ⁻¹(x+2)+ ⁻¹(x-2)- ⁻¹ ( 1 2 )=0 & ⁻¹ ( (x+2)+(x-2) 1-(x+2)(x-2) )- ⁻¹ ( 1 2 )=0 & ⁻¹ ( 2 x 5-x^2 )- ⁻¹ ( 1 2 )=0 & ⁻¹ ( 2 x 5-x^2 - 1 2 1+ 2 x 5-x^2 1 2 )=0 & ⁻¹ ( x^2+4 x-5 -x^2+x+5 )=0 & x^2+4 x-5=0 & x=-5 or x=1 aligned
