Hope u like my process
=====================
(ii) x² - 2ax +(a² - b²) =0
or, x² - 2ax + (a +b) (a-b) =0
or, x² - {(a+b) +(a-b)}x + (a+b) (a-b) =0
or, x² - (a+b)x - (a-b)x + (a +b) (a-b) =0
or, x{x-(a+b)} - (a-b) {x-(a+b)} =0
or, (x- a-b) (x - a +b) =0
So... The possible roots are..
x = a + b
and
x = a - b.
