Let a and b be non-negative real numbers. If x+a x = b , then | a x - x |=
Options
- Aa^2-b^2+1
- Bb^2-a^2+1
- C1+a^2+b^2
- Da^2+b^2-1
Correct answer
A. a^2-b^2+1
Step-by-step solution
Given x + a x = b ...(i) Let a x - x = ...(ii) on squanity and adding (i) and (ii) we got a ^2+1= b ^2+ ^2 a ^2- b ^2+1
