If ( ⁻¹ x) = ( ⁻¹ a b^2 - a^2 ) , then the value of x is
Options
- Ab 2b^2 + a^2
- B2b^2 - a^2 b
- C2b^2 + a^2 b
- Db 2b^2 - a^2
Correct answer
D. b 2b^2 - a^2
Step-by-step solution
Let ⁻¹ x = = x = = x 1 - x^2 Let ⁻¹ a b^2 - a^2 = = a b^2 - a^2 = 1 + ^2 = 1 + a^2 b^2 - a^2 = b b^2 - a^2 Given = , we have: x 1 - x^2 = b b^2 - a^2 Squaring both sides: x^2 1 - x^2 = b^2 b^2 - a^2 x^2(b^2 - a^2) = b^2(1 - x^2) x^2 b^2 - x^2 a^2 = b^2 - x^2 b^2 x^2(2b^2 - a^2) = b^2 x^2 = b^2 2b^2 - a^2 x = b 2b^2 - a^2 Answer: b 2b^2 - a^2
