Question

The roots of the equation 1a+b+x=(1a)+(1b)+(1x) are?
  1. -a ,-b
  2. (a-b), (a+b)


Solution

The correct option is A -a ,-b

Take a=1 and b=1, we basically need to find the value of x. now, the equation becomes  1(2+x)=2+1x

x2+2x+1=0 
solving for x, we get x=-1,-1

Which is nothing but -a,-b. option c is the answer
