If two equations

{x^2} + {a^2} = 1 - 2ax

and

{x^2} + {b^2} = 1 - 2bx

have only one common root, then

View answer and explanation

Correct option: C

a - b = 2

Option C (a - b = 2) is correct because by applying the condition for common roots and simplifying the resulting equation, we arrive at a - b = 2.
