Question

$\frac{x + a}{x - a} = \frac{b - a}{b + a}$
​

Answer 1

Answer:

a = 0 or x = - b

Step-by-step explanation:

x+a/x - a = b - a/b + a

Cross multiply the above.

=> (x + a)(b + a) = (x - a)(b - a)

=> bx + ab + ax + ab = bx - ab - ax + ab

=> 2ab + 2ax = 0

=> 2a(b+x) = 0

=> 2a = 0 and b + x = 0

=> a = 0 or x = - b.
